Thanks Canis!
By the way, is there something like a lucid day dream or something, or some kind of super detailed day dream, as I this morning I had a very realistic and intense dream, but I don't know whether I was actually asleep or not. It was just like a dream but I didn't kind of jolt awake from it or anything, when it finished I instantly knew what was going on and got up straight away, like it was a day dream. I know this sounds weird but I'm just wondering if there are lucid day dreams or something similar to let you have extremely detailed and realistic day dreams.
