I hear someone call my name quite frequently. The worst I had was a long monlogue by a halucination while I was on Serazone (technically hypnagogic, in reality simply outrageous, brogue and all). My olfactory come on with bloodpressure falls and yep, smells like blood.

right now i am having some perceptual problems, but they say that's because I am having such bad swelling in my sinuses that one of my eyes sin't able to move properly, so I'm seeing some things in 3D that aren't supposed to be. This has also happened to me on some types of meds. Not true hallucinations, though.
