Come Into My Brain
by Robert Silverberg
Dane Harrell held the thought-helmet tightly between his hands, and, before putting it on, glanced over at the bound, writhing alien sitting opposite him. The alien snarled defiantly at him.
“You’re sure you want to go through with this?” asked Dr. Phelps.
Harrell nodded. “I volunteered, didn’t I? I said I’d take a look inside this buzzard’s brain, and I’m going to do it. If I don’t come up in half an hour, come get me.”
“Right.”
Harrell slipped the cool bulk of the thought-helmet over his head and signalled to the scientist, who pulled the actuator switch. Harrell shuddered as psionic current surged through him; he stiffened, wriggled, and felt himself glide out of his body, hover incorporeally in the air between his now soulless shell and the alien bound opposite.
Remember, you volunteered, he told himself.
He hung for a moment outside the alien’s skull; then he drifted downward and in. He had entered the alien’s mind. Whether he would emerge alive, and with the troop-deployment data—well, that was another matter entirely.
The patrol-ships of the Terran outpost on Planetoid 113 had discovered the alien scout a week before. The Dimellian spy was lurking about the outermost reaches of the Terran safety zone when he was caught.
It wasn’t often that Earth captured a Dimellian alive, and so the Outpost resolved to comb as much information from the alien as possible. The Earth-Dimell war was four years old; neither side had succeeded in scoring a decisive victory over the other. It was believed that Dimell was massing its fleets for an all-out attack on Earth itself; confirmation of this from the captured scout would make Terran defensive tactics considerably more sound.
But the Dimellian resisted all forms of brainwashing, until Phelps, the Base Psych-man, came forth with the experimental thought-helmet. Volunteers were requested; Harrell spoke up first. Now, wearing the thought-helmet, he plunged deep into the unknown areas of the Dimellian’s mind, hoping to emerge with high-order military secrets.
His first impression was of thick grey murk—so thick it could be cut. Using a swimming motion, Harrell drifted downward, toward the light in the distance. It was a long way down; he floated, eerily, in free-fall.
Finally he touched ground. It yielded under him spongily, but it was solid. He looked around. The place was alien: coarse crumbly red soil, giant spike-leaved trees that shot up hundreds of feet overhead, brutal-looking birds squawking and chattering in the low branches.
It looked just like the tridim solidos of Dimell he had seen. Well, why not? Why shouldn’t the inside of a man’s mind—or an alien’s, for that matter, resemble his home world?
Cautiously, Harrell started to walk. Mountains rose in the dim distance, and he could see, glittering on a mountaintop far beyond him, the white bulk of an armored castle. Of course! His imaginative mind realized at once that there was where the Dimellian guarded the precious secrets; up there, on the mountain, was his goal.
He started to walk.
Low-hanging vines obscured his way; he conjured up a machete and cut them down. The weapon felt firm and real in his hand—but he paused to realize that not even the hand was real; all this was but an imaginative projection.
The castle was further away than he had thought, he saw, after he had walked for perhaps fifteen minutes. There was no telling duration inside the alien’s skull, either. Or distance. The castle seemed just as distant now as when he had begun, and his fifteen-minute journey through the jungle had tired him.
Suddenly demonic laughter sounded up ahead in the jungle. Harsh, ugly laughter.
And the Dimellian appeared, slashing his way through the vines with swashbuckling abandon.
“Get out of my mind, Earthman!”
The Dimellian was larger than life, and twice as ugly. It was an idealized, self-glorified mental image Harrell faced.
The captured Dimellian was about five feet tall, thick-shouldered, with sturdy, corded arms and supplementary tentacles sprouting from its shoulders; its skin was green and leathery, dotted with toad-like warts.
Harrell now saw a creature close to nine feet tall, swaggering, with a mighty barrel of a chest and a huge broadsword clutched in one of its arms. The tentacles writhed purposefully.
“You know why I’m here, alien. I want to know certain facts. And I’m not getting out of your mind until I’ve wrung them from you.”
The alien’s lipless mouth curved upward in a bleak smile. “Big words, little Earthman. But first you’ll have to vanquish me.”
And the Dimellian stepped forward.
Harrell met the downcrashing blow of the alien’s broadsword fully; the shock of impact sent numbing shivers up his arm as far as his shoulder, but he held on and turned aside the blow. It wasn’t fair; the Dimellian had a vaster reach than he could ever hope for—
No! He saw there was no reason why he couldn’t control the size of his own mental image. Instantly he was ten feet high, and advancing remorselessly toward the alien.
Swords clashed clangorously; the forest-birds screamed. Harrell drove the alien back…back…
And the Dimellian was eleven feet high.
“We can keep this up forever,” Harrell said. “Getting larger and larger. This is only a mental conflict.” He shot up until he again towered a foot above the alien’s head. He swung downward twohandedly with the machete—
The alien vanished.
And reappeared five feet to the right, grinning evilly. “Enough of this foolishness, Earthman. Physical conflict will be endless stalemate, since we’re only mental projections, both of us. You’re beaten; there’s no possible way you can defeat me, or I defeat you. Don’t waste your time and mine. Get out of my mind!”
Harrell shook his head doggedly. “I’m in here to do a job, and I’m not leaving until I’ve done it.” He sprang forward, sword high, and thrust down at the grinning Dimellian.
Again the Dimellian sidestepped. Harrell’s sword cut air.
“Don’t tire yourself out, Earthman,” the alien said mockingly, and vanished.
Harrell stood alone in the heart of the steaming jungle, leaning on his sword. Maybe they were only mental projections, he thought, but a mental projection could still get thoroughly drenched with its own mental sweat.
The castle still gleamed enigmatically on the distant mountain. He couldn’t get there by walking—at least, it hadn’t seemed to draw any nearer during his jaunt through the jungle. And hand-to-hand combat with the alien was fruitless, it appeared. A fight in which both participants could change size at will, vanish, reappear, and do other such things was as pointless as a game of poker with every card wild.
But there had to be a way. Mental attack? Perhaps that would crumble the alien’s defenses.
He sent out a beam of thought, directed up at the castle. Can you hear me, alien?
Mental laughter echoed mockingly back. Of course, Earthman. What troubles you?
Harrell made no reply. He stood silently, concentrating, marshalling his powers. Then he hurled a bolt of mental energy with all his strength toward the mocking voice.
The jungle shuddered as it struck home. The ground lurched wildly, like an animal’s back; trees tumbled, the sky bent. Harrell saw he had scored a hit; the alien’s concentration had wavered, distorting the scenery.
But there was quick recovery. Again the mocking laughter. Harrell knew that the alien had shrugged off the blow.
