Sounds very normal to me. You have been under a lot of stress. A lot can happen. Losing a parent, especially one that was your best friend is very tramatic. Some people hear the person's voice or think they see them. My parents have been gone for 6-8 years and were abusive and I still think I hear their voice or see someone that looks like them or even see a name that's close to there's. Strange things can happen.

Take it easy, eat healthy and continue your life as you always have. Take care of yourself and you will be fine.
