Sleep Disorders Community

I will start off by saying I am a morning person and I am awake at 630am Monday to Friday and on the go for most of the day in between work and school and I am often tired during the day. Normally the most tired around 3:00 and can easily fall asleep on the couch while watch tv or doing homework. It is very rare that I am up past 11 on most nights I am in bed by 10 and fall asleep with in a minute or 2 after hitting the pillow. Atleast once a week (sometimes more) my boyfriend will ask me if I remember sitting up during the middle of the night and talking to him. There has been other nights where I will get out of bed and do odd things like start folding clothes and then I wake up and realize I am not in my bed or I will not realize that I got up and the next day my boyfriend will ask me if I recall doing those types of things. There has also been times where I will ask him questions or appear frightened asking "who is that?", "what's over there" and he will tell me nothing is there and to go to sleep and I respond with okay yet the next morning I dont recall doing any of this. I do toss and turn quite a bit in my sleep due to just being uncomfortable. My boyfriend thinks that its possible that I never fully reach REM sleep and that is why I am tired a lot the next day. I looked online to see if I should get any help for this but everything I read said that as long as it is not disturbing myself or others then I shouldnt be concerned. Has anyone else had similar issues? What are your thoughts?? Should I get it checked out?
