Hey guys this is my first time posting but I have been observing for a while. I had My first Lucid dream two days ago! It was amazing. I have a question about it though. Here's the dream:
I am on a play ground in the summer somewhere with a friend. He says some thing strange and I tried to look at him but couldn't see his face..Then I said to him that this is a dream. He said prove it. Then for some reason I tried to squeeze my hand to make flames shoot out but only smoke came out. Then I guess I just forgot I was dreaming because I don't remember the rest.

The question is why couldn't I shoot fire? If there are any experienced Lucid Dreamers can you tell me what happened?
