Let's not. What you're describing are known as pseudo-hallucinations. i.e. The floor looks wavy and like it's moving, that sort of thing. A hallucination is seeing something (and is always visual) that isn't there, such as a person or object. Delusion is believing these are real and endorsing as real, but delusion often occurs without hallucination, such as believing someone is in the room without visually perceiving them. Delusion is somewhat related to fantasy, it all depends on whether it is believed to be real. Aural hallucinations are, of course, hearing things that aren't there.

The term used by people that seek these things out appears to be “visual effects”[0] and it apparently includes any sort of change in visual perception. I have never come across the term pseudo-hallucination to describe these phenomena before this comment.

From the linked page: “The term is not widely used in the psychiatric and medical fields, as it is considered ambiguous.”
