I'm not really new to this, I have been reading up and doing a lot of experiments with lucid dreams, however I was curious about this other thing because I didn't really understand it. I was meditating before I went to bed. I meditated for about 20 minutes when I was starting to feel real comfortable and my thoughts were empty when all of a sudden I see this image of me (1st person might I add) sitting on one of my chairs, with an xbox controller in my hand. I get scared for some weird reason, I don't know why. It was not scary but I read up and found out that these images tend to give a feeling of violence or something like that. So I try my hardest to not get excited, the image was so clear!. So I keep my mind clear and let the dreams form, I see a few more things (just the usual paterns and or lights). I was doing so good until eventually for some weird reason (anyone know why? It has also happened during other sessions), My left arm moves by itself. So at that point I just start writhing in bed because I don't want to have to go through all that again, but at least I am happy because the experience was something else!!!

So my question is, what could have happened if I had continued with the meditation? Would I have entered a dream state eventually (If I didn't fall asleep?

I really love lucid dreams and respect everything about them. Anybody want to share an experience where you self meditated? Any tips or advice?
Thanks
