I just recently started having weird experiences at night. I awake and start talking to a loved one, family member or friend who is in my bedroom. The conversation usually goes like "what are you doing here". Sometimes they say they are just getting something but one time my ex was at the end of my bed and I said "What are you doing here" - he replied "I'm not really here". I was awake because I remember how mad I got at him. Although he has a key to my house, he was not staying there. I said "you can't be here" and he replied "I'm not here". So, I then had the same experience seeing my nephew, who I know for sure was not in my room. Just recently I've been having a similar experience but with it being my son. I awake in the night and he is on the other side of my king sized bed. Last night I asked him if he's okay and he said "yes, I'm okay" and went to sleep. That never really happened. It's driving me crazy.
