There are so many Necros on the forums, we should just consider them as regular posts now. -_-
On the Original Topic, I had one lucid dream a year back. It was probably the best thing I've done in my whole life, only problem, is that it felt like it lasted a week. I'm not even kidding, it felt like it lasted 7 days in real life. When I woke up, I didn't even realize it went on for so long. An 8 hour sleep felt like a week, it was a weird illusion. o_0
I've had them from time to time, but I usually force myself to wake up to prevent myself from getting Sleep Paralysis. That, is some weird stuff. I heard you freeze in your sleep, and see things you're not supposed to see. If that happened to me, I would have to sign in to a mental hospital.
