Well I once went through about half a year where i got really into lucid dreaming and figured out how to do it while I was asleep, but one day I was dreaming and I did the trick where you look at works, look away, and then look back and if they change you are dreaming and control your mind. The words actually were the same, so I went 4 minutes trying to make my friend tell me I was dreaming, and I decided running into a wall would be a good idea so i jumped into it using my shoulder and then woke up instantly to severe shoulder pain. I only am able to lucid dream on occasion now.

But no, that never happened to me.
