A description of the experience
H Kluver – Mescal and Mechanisms of Hallucination 
He saw fretwork before his eyes, that his arms, hands and fingers turned into fretwork. There was no difference between the fretwork and himself, between inside and outside. All objects in the room and the walls changed into fretwork and thus became identical with him. While writing the words turned into fretwork and there was therefore, an identity of fretwork and handwriting. ‘The fretwork is I’.
