I was just looking back at my dream journal from 1992. In one particularly long account, I realise I am dreaming part way through and then attempt to modify the dream as I had done many times prior to that. What I attempted to do was make a castle appear in front of me, in which I intended to explore. What did appear in front of me was a small toy plastic castle. As I approached it I realised it was a detailed model of castle and perfect in everyway, but it was tiny. I tried to make it grow in size but however much I tried it stayed the size it was.
Most of the time when I try something out it happens as I intended. Sometimes the same things works in one dream but not in another. For example, in one lucid dream I tried to make a rock burst into flame and it didn't, but I could quite easily fly in that dream. In another lucid dream I set a person on fire with my mind (knowing it was a dream of course), which seems very similar to trying to make a rock burst into flame.
It yet another example, I make a pack of cards float across the room to me. I then take out 3 cards and make them float across the room in a triangular formation. I then attempt to make all 52 cards float across the room in a wave like motion and this doesn't work at all.
Has anyone else noticed that sometimes you can change the dream at will, but sometimes it refuses to budge?
