HIS voice came to us again. He said, at first, that he saw nothing in the abyss below him. Then he gasped, swayed, and almost lost his balance. We could see the sweat standing out on his brow and neck, soaking his blue shirt. There were things in the abyss, he said in hoarse tones, great shapes that were like blobs of utter blackness, yet which he knew to be alive. From the central masses of their beings he could see them shoot forth incredibly long, filamentine tentacles. They moved themselves forward and backward — horizontally, but could not move vertically, it seemed. They were, he thought, nothing but living shadows.
Robert A.W. Lowndes (THE ABYSS)

I had no weapon nor did I feel the need of any; a strong, athletic youth, I was in addition an amateur boxer of ability, with a terrific punch in either hand. Now all the primal instincts surged redly within me; I was a cave man bent on vengeance against a tribe who sought to steal a woman of my family. I did not fear–I only wished to close with them. Aye, I recognized these–I knew them of old and all the old wars rose and roared within the misty caverns of my soul. Hate leaped in me as in the old days when men of my blood came from the North. Aye, though the whole spawn of Hell rise up from those caverns which honeycomb the moors.–Robert E. Howard “The Little People”

“It was the eyes that grew dim. Little by little he came to know that some day the dream would not end when he turned away to go home, but would lead him down the gorge out of which the vision rose. She was nearer now when she beckoned to him. Her cheeks were not livid like those of the dead, but pale with starvation, with the furious and unappeased physical hunger of her eyes that devoured him. They feasted on his soul and cast a spell over him, and at last they were close to his own and held him. He could not tell whether her breath was as hot as fire or as cold as ice; he could not tell whether her red lips burned his or froze them, or whether her five fingers on his wrists seared scorching scars or bit his flesh like frost; he could not tell whether he was awake or asleep, whether she was alive or dead, but he knew that she loved him, she alone of all creatures, earthly or unearthly, and her spell had power over him.”–Francis Marion Crawford (For the Blood is the Life)

“The corridor to Comsos House twisted, as did nearly all corridors in Big Magnet, and Powell stood at the entrance again. But they heard, rather muffled, McReady’s sudden shout. There was a savage flurry of blows, dull ch-thunk—shluff sounds. “Bar—Bar—for God’s sake—”And a curious, savage mewing scream, silenced before even Powell had reached the bend.”–John W. Campbell (Frozen Hell)

“White-hot agony lanced through his breast, throbbed in his eyeballs. His head seemed to be swelling, growing larger and larger; and suddenly he heard the exultant squealing of the rats. He began to scream insanely but could not drown them out. For a moment he thrashed about hysterically within his narrow prison, and then he was quiet, gasping for air. His eyelids closed, his blackened tongue protruded, and he sank down into the blackness of death with the mad squealing of the rats dinning in his ears.”–Henry Kuttner (The Graveyard Rats)

And as I writhe in my guilty agony, frantic to save the city whose peril every moment grows, and vainly striving to shake off this unnatural dream of a house of stone and brick south of a sinister swamp and a cemetery on a low hillock; the Pole Star, evil and monstrous, leers down from the black vault, winking hideously like an insane watching eye which strives to convey some strange message, yet recalls nothing save that it once had a message to convey.–H.P. Lovecraft (Polaris)
