Lack of details, sense of self in dreams

I don't remember my dreams very often, and when I do, they're often recollected by my mind as these short, vague scenes.

I would remember what sort of happened, like a general plot to a story, or random scenes from a movie... so in a way I remember what sort of dreams I had, but never anything in detail.

In a way, it's almost like my memory of the dream are recollected as photographic images of various fleeting moments.

If I'm having an erotic encounter, I would remember the position of the sexual encounter, but never what the girl looks like or what I look like, or from my POV... it's almost as if I'm watching a scene play out, yet the memory is telling me that the character in this story is me.

Needless to say, this lacking realization of my sense of self during a dream has made it very hard to do any reality check.

Does this simply mean that I just need to work on remembering my dreams better? That at the moment, I'm only able to recollect the "summary" and few memorable imagery from the dream I was having?

Do you practice WBTB? Usually my dreams are like that until after WBTB. The later dreams are much better.
