odd dreams, no rest

So lately I have been having sudden short strange dreams and I find myself acting out on them. They are not violent dreams just strange. They don't have a story behind them it is just sudden. For example. One night I suddenly dreamt my 10 month nephew was about to fall off the headboard to my bed. And I was trying to hold him up so he wouldnt fall but i was struggling. (My head board is not that tall but in my dream it was) Then I must have woken up bc I realized I was actually kneeling up by my headboard pushing up my curtain that was wrapped around the post. My heart was racing and it took me a bit to fall back asleep.
Last night I was dreaming I was trying to hold something up ( only thing i remember in this dream) and I was woken up when my bf asked what I was reaching for? That's when I realized I was sitting up with my arms extended out and upwards.
This has been going on for about 2-3 months now and I don't know why it's happening. Has anyone else experienced this or knows what this would be called?

If you act out your dreams in waking life, you have what's called REM behavior disorder. You should visit a doctor.
