I am currently attempting to enter a LD through the WILD technique, but I wish to share a story (more like a warning).
I have a friend who's name I won't share, who has done lucid dreaming for some time, and was sharing his experiences with me (he made me want to do it myself :razz:). Anyways, in August this year, my friend came to my house looking frustrated and shocked me by telling me that I am not here and that he is dreaming! I told him it's all real (because it obviously was, but you never know). He then told me that he has observed lots of dreamsigns and that he can't read any text. He said that it is clearly a dream but that he cannot wake up, that he has been in it for ever. He said that everything is different and that he can even get all the effects he was getting while LD-ing (strobing of vision while turning around, text unreadable/changing, the buildings were not where he remembered them, I looked different, his parents are never home, etc). I became very freaked out and I took him into the house to give him a glass of Sprite and cool down, maybe watch some TV, but he was not the way I knew him, he was scared and was sometimes staring blankly. Eventually, his parents came home from work and phoned me because they were worried becuase my friend was not home. I told them that something is wrong with him, and they came over immediately. The next day, his parents took him to a doctor and, after days of testing, the doctor concluded that he has schizophrenia :cry: . Apparently, his LD hobby became the main plot for his schizo phantasy, in which he was dreaming and everyone and everything around him was unreal. He is doing a lot better now (he's on medication). I am particularly concerned that practicing lucid dreaming may reveal latent schizophrenia in people who might never develop it at all. I am honestly a bit scared of doing it myself because my family too has a few (dead) members who have been schizophrenic.
