I'm curious as to know if stress can prohibit you from dreaming. For example, I have an injury to my shoulder that sometimes keeps me up at night. I've also been stressed out for other reason, but I don't feel as though it would be polite to post them here. I was sleeping earlier and knew I was resting. So can stress keep one from dreaming? I nearly had two lucid dreams in January, but thanks to the alarm clock and getting too excited I woke up. What's the best way to dream and attain lucidity for you during stressful times?

I've also discovered that since I've begun to practice Lucid Dreaming that I can recall dreams I had six or seven years ago. Is this normal?

I apologize if I posted this in the wrong forum. If a moderator could move it to the correct one, that would be appreciated.
