I'm new here and am interested in seeing what this situation below is classified as.
Since I was 7 or so I remember dreaming in this format:
1) I/Something would do nonsensical dream stuff and it is rather pleasant.
2) I would come to the realization that I am having a dream.
3) I then would tell someone within the dream that they in fact are not real.
4) The dream denizens would then become hostile, and hostility would seem to emanate from everything.

After 2-4 weeks of ^this^ when I realized that I was in a dream I would just play along nervously knowing that it wasn't real.
It felt as if I had no control.

Once this^ stuff subsided when I was 10 to would get night terrors relating usually relating to hostile extraterrestrials.

Then I started to forget dreams more and more as I would generally avoid sleep until the last possible moment.
