i know my anxiety has caused all kinds of hallucinating in the past. most common is when driving. buildings on the side of the road exploding, trucks falling on top of me, massive nascar type crashes in front of me with the cars exploding into fire balls pieces flying every which way and me ducking to not be hit. it all seems very real but it disappears in an instant, just like your body. i got on buspar for anxiety and it hasnt happened since.
