My husband talks to myself all the time... and will have full conversations!
So he often knows what will happen when he has the conversation with me,
because he has "already had the conversation" LOL

Our "voices" are inside our heads
if you hear voices that are outside your head (like if you hear it and then you look around a room to see who said it,
that may be a schizophrenic episode (but you know we at PC can not diagnose you, so I highly recommend you talk to a professional)
