Every time I try to OBE, and sometimes when I'm just walking through the house I get sudden, strong, pictures of, what are best described as monsters, horrible white bodied humanoid figures to monks with no faces, I have never achieved an OBE but when I try, my dreams that night are particularly vivid, and although I know I am dreaming, I can't seem to lucid dream... Are these images just a result of my overactive imagination? or is it something more?
