I’ve been doing this lately. Basically I read a lot either programming or just browsing forums etc so I dream about a lot of text almost every night. Lately I’ve got to a point where I see some text (in a dream) and try to read it and it’s gibberish. So when I see this text my mind immediately knows that I’m dreaming and im able to “take control” and walk around the dream land. It isn’t anything special and usually I wake up after a few minutes of walking around in confusing land, but this may be because I’ve only just started. I’m not sure why I’m only now beginning to tell this gibberish text, as I wasn’t intending to lucid dream and until it happened I thought it was a myth.
