Just the other day I clearly heard a friend call out my name but he was not there. Many times in the past I have heard my name called or heard a voice talking to me only to find that, after investigation, there was no-one around who spoke. Often I hear TV's and radios that are not on, or music in the background. Only a couple of times have I seen things that were not there, like bugs all over the floor or people walking by. Mostly the hallucinations haven't bothered me much but a couple of times I was seriously freaked out by them.
