You should try out some better books. Have a go at this passage from A Portrait Of The Artist As A Young Man, by Joyce, wherein the protagonist Stephen Dedalus is losing his mind after having spent a week being whipped into a religious frenzy. He is alone in his room pondering his frequent visits to brothels:
> He closed the door and, walking swiftly to the bed, knelt beside it and covered his face with his hands. His hands were cold and damp and his limbs ached with chill. Bodily unrest and chill and weariness beset him, routing his thoughts. Why was he kneeling there like a child saying his evening prayers? To be alone with his soul, to examine his conscience, to meet his sins face to face, to recall their times and manners and circumstances, to weep over them. He could not weep. He could not summon them to his memory. He felt only an ache of soul and body, his whole being, memory, will, understanding, flesh, benumbed and weary.
>
> That was the work of devils, to scatter his thoughts and over-cloud his conscience, assailing him at the gates of the cowardly and sin-corrupted flesh: and, praying God timidly to forgive him his weakness, he crawled up on to the bed and, wrapping the blankets closely about him, covered his face again with his hands. He had sinned. He had sinned so deeply against heaven and before God that he was not worthy to be called God's child.
>
> Could it be that he, Stephen Dedalus, had done those things? His conscience sighed in answer. Yes, he had done them, secretly, filthily, time after time, and, hardened in sinful impenitence, he had dared to wear the mask of holiness before the tabernacle itself while his soul within was a living mass of corruption. How came it that God had not struck him dead? The leprous company of his sins closed about him, breathing upon him, bending over him from all sides. He strove to forget them in an act of prayer, huddling his limbs closer together and binding down his eyelids: but the senses of his soul would not be bound and, though his eyes were shut fast, he saw the places where he had sinned and, though his ears were tightly covered, he heard. He desired with all his will not to hear or see. He desired till his frame shook under the strain of his desire and until the senses of his soul closed. They closed for an instant and then opened. He saw.

> A field of stiff weeds and thistles and tufted nettle-bunches. Thick among the tufts of rank stiff growth lay battered canisters and clots and coils of solid excrement. A faint marshlight struggling upwards from all the ordure through the bristling grey-green weeds. An evil smell, faint and foul as the light, curled upwards sluggishly out of the canisters and from the stale crusted dung.
>
> Creatures were in the field: one, three, six: creatures were moving in the field, hither and thither. Goatish creatures with human faces, hornybrowed, lightly bearded and grey as india-rubber. The malice of evil glittered in their hard eyes, as they moved hither and thither, trailing their long tails behind them. A rictus of cruel malignity lit up greyly their old bony faces. One was clasping about his ribs a torn flannel waistcoat, another complained monotonously as his beard stuck in the tufted weeds. Soft language issued from their spittleless lips as they swished in slow circles round and round the field, winding hither and thither through the weeds, dragging their long tails amid the rattling canisters. They moved in slow circles, circling closer and closer to enclose, to enclose, soft language issuing from their lips, their long swishing tails besmeared with stale shite, thrusting upwards their terrific faces...

> Help!
>
> He flung the blankets from him madly to free his face and neck. That was his hell. God had allowed him to see the hell reserved for his sins: stinking, bestial, malignant, a hell of lecherous goatish fiends. For him! For him!
>
> He sprang from the bed, the reeking odour pouring down his throat, clogging and revolting his entrails. Air! The air of heaven! He stumbled towards the window, groaning and almost fainting with sickness. At the washstand a convulsion seized him within; and, clasping his cold forehead wildly, he vomited profusely in agony.
