Am I Dreaming?

I keep having the weirdest "dreams" allowing me to meet people that I have never realistically met before.

I describe these dreams as my night terrors, as they usually involve horrific scenes involving people that I can view fully, and connect with them on a personal level, although they are not real.

My most recent one being last night, in the dream at first, I was in work talking to my boyfriends mother when I fainted I thought I woke up at this stage to someone poking me playfully in the back, I tried to grab their arm but kept pulling odd items from under me instead, then I finally reached the hand and turned to see a beautiful, smiling middle aged woman that I have never seen before, she was standing by my bed and said hello, but got aggravated when I cried out. Then I "woke" again, started to walk down the stairs, where again, I met her and she waved., I ran upstairs to find another girl sitting on my bed. She showed me a scene at a swimming pool where there had been an accident where many people were injured, including some of my own friends. Two people had died. I could actually feel the pain and fear.

When I finally woke in my room, I was unsure of my whereabouts and even right now I feel drained and drifting. This is one of these many experiences. I'm not sure what this means, but I'm sure somebody is trying to tell me something. Sometimes these people are good, and sometimes when they are bad, they appear as little dark creatures rather than people.

If this is not exactly a psychic experience, why can I see these faces, and their clothes, and features and speak to them as if I understand them and their please?
