[so_tired_24/7]

Hello,
I am just trying to self diagnose here. In the middle of a dream I get up and am talking to people who I can see (but who are in my dream) It is like they are really there. Sometimes I walk around - Usually the people in my dreams are in trouble and need my help so I am trying to get to them. I used to wake up thinking my son was in the closet and I was trying to find him. It has gotten worse now. I get up 3-4 times a night, I am so tired during the day I have to fight to stay awake. I do not have problems snoring, or with sleep apnea (that I know of) I go to the gym at least 5 times a week, and I eat fairly healthy. My husband is so used to my sleep talking and walking that he sleeps right through it now. Please any advice?
