I get the auditory ones sometimes. It's very strange! Sometimes it's someone I know saying my name, but other times it's a completely strange voice, saying a word or a short nonsense phrase. And I know I didn't hear it with my actual ears, but it is as real sounding as if I had. It's very dreamlike. I had it a lot while I was ill with a fever a couple of years ago. Other than that, it usually happens as I'm trying to fall asleep but am still conscious.
