Oh, I've gotten hallucinations while driving. Luckily nothing major. I also tend to get hypnagogic hallucinations when I'm stressed.

Someone I knew was all "oh man it must be ~~so fun~~ to hallucinate when you're going to sleep ~~I wish I could experience it~~" and I just stared at her because some nights I had seriously contemplated whether stabbing my eardrums would stop me from repeatedly hearing my mobile phone's ringtone (even though I had switched it off).
