Recently I have had several what would be classed as lucid dreams, in that I am aware I am dreaming. Usually I wake up in my bed and sit up and when I look back I can still see myself sleeping. When I move around the room I seem to be able to float, almost like a spaceman on the moon. When I realise I'm dreaming I wake myself. I then find myself in another lucid dream in the same situation, in my bedroom in the dark. I don't seem to have control over my surroundings. I can't make things appear for example. I tried to look out the window at one point but when I pulled the curtain back the whole window was black. This usualy happens several times until I do eventually waken up properly. Is this a lucid dream and how do I go about having more control of them?
