Le Horla by Guy de Maupassant

The Horla takes you inside the head of a man who feels an invisible presence in his life. This presence is none other than the Horla. The character is suffering from a psychiatric disorder that makes him go through several psychic states. Up to dementia! Paranoia, hallucinations, anxiety attacks, sleep paralysis. He speaks in the first person using “I” so that the reader can identify with him or her. In the end you and this person will become one. You will imagine exactly all his psychic states with the help of every detail of them.
