Mine was voices of people who had passed that were close to me. It came from inside my mind. No, I do not feel there were ghosts or some other phenomena speaking to me. I believe it was a manifestation of my subconscious. I had some memories of childhood trauma resurface and the voices spoke to me and tried to help explain what happened to me when I was a child. They behaved like guides or therapists. I found them comforting and didn't second guess their presence. I went into heavy psychosis shortly after this happened. I know now that I need help asap if it ever happens again. The voices had good intent, but I was going through PTSD as the memories came up, so I see them as a sign something was clearly wrong.
