I have lucid dreams quite often. At one point I could control what happened in my dreamstate and was aware that I was dreaming. sadly, I abused this gift by asking the people in my dreams if they were aware they were dreaming or by having "inappropreate relations" with them! lol
Seriously though, when a very close friend of mine died of cancer about 7 years ago I had a few lucid dreams of him which were amazing. He also gave me a message in one of them on the eve of 9/11 which was startling.
The last lucid dream I had was about a month a go. I wish I could have them at will every night.
