Not sure what this is called

[Aras]

I Had just woken up, was very tired and just couldn't get up. I
started drifting in and out of sleep, I was laying on my stomach,
something I rarely do, and then the buzzing started, and man
it was getting extremely loud, scary loud, all over my head, I
said to myself, "oh no.." then I was trying to move, I think I
lifted my head and I think I had my eyes open, but it seemed
like everything was in gray colors and very static...it was also very very hard to lift my head, everything felt so heavy.  I'm
not sure If I just gave up, then I was able to open my
eyes and turn over and wake up.

A few minutes after that happened, then this followed:



I drifted back to sleep again, this time I was laying on my side. The buzzing started again, but this time it was not nearly as loud as the
previous time, I also felt someone actually start to lay down
next to me. I could feel the bed dip when they started to lay down and felt them up against me. I felt very heavy and hardly able to move.. I kept  wondering who was laying next to me, but I couldn't turn over
I just kind of kept trying to move, very slowly, and finally
was able to move and turn over and see no one there. But
the feeling that someone was there was very intense.

So... If anyone has had this happen or know what it could be, I appreciate any comments.
Thanks,
Aras
