A few years ago I had fairly severe crohns disease and was put on a high dosage of prednisone for about five months. During that time I had very vivid dreams and, when combined with the right mental exercises lucid dreams. Since I went off of the medication that phenomenon has disappeared. I have been trying to get back into lucid dreaming with limited success. I asked a sleep doctor about whether prednisone would have that side effect and he said that my brain was wired differently and that it would go straight to my limbic system. Which would create the vivid/lucid dreams I had experienced. I googled this and found absolutely no research on it so I was curious. Has anyone else had this particular side effect?
