Yes I think it is more likely that you are having normal dreams and that you just need to do things to help with recall. Maybe if you can, you could set alarms to go off towards the end of the night, to wake you up occasionally during the most likely time that you will be in REM. Then without moving try to remember what you were dreaming about. Try to get into your conscious mind before you get up. Then immediately go write it down as soon as you can remember it.
