Hi Damla,
not quite a usual dream yes. Rooms with no window frequently appear in my retrievals. And detached hands, arms and legs I saw once in a HemiSync exercise of Focus 23, the retrieval area.
  If you think about what could you have done in that situation, I usually at first say "hello". Mostly something is happening then. Or I would ask "Hey, for how long are you doing this >arms and legs< game?" But I never plan my actions in this field. I somehow am smarter when I'm in the situation, more than when I'm in C1 state.
Bye, Spooky

A man and a woman together? In a period of about a week, I did three retrievels of a man and a woman together (three different couples, if you can call them that), and each time it was a bad vibes scene. I didn't do them during a dream though.

It seems as if the people you saw were stuck together. You might meditate a bit, and then imagine yourself retrieving them. Try to introduce them to a guide.

If it works, it works. If it doesn't, it doesn't.

If after you start imagining a retrievel, and perhaps thoughts and images start entering your mind without you having a chance to imagine them, then perhaps something actually happened.

Otherwise, is there a relationship you're trapped in, and it seems like there is no way out? Or perhaps somebody you know. In a way, if a guy gets too controlling of somebody he's in a relationship with, he basically takes controll of that person's body, and uses it within his own self created prison.
