I used to think it was all about seeing music, tasting words and see numbers as colours. But now a psych professor told me I might have this and this is why I perceive entities that others cannot see.

I did not understand the explanation at all. I am googling but finding nothing. He is sure I do not dissociate like my doc thinks.

None think I have psychosis. It is like I can see into other layers of reality. If it is real, fine, but if it is synesthesia and from inside me I want to know how it happens.

Any info welcome.
