Hi guys, this is my first post here on DV though I have been browsing the forums for some time now. I have finally gotten enough interest in LD'ing and now I have a question on SP. I have gone through several threads on SP'ing and I have noticed a common way to know you are under SP is to see shadows or hallucinations. The problem, my room is literally pitch black at night and the most of the time I wear a sleep mask to prevent light from my window in the morning. Are there any other significantly noticeable symptoms that would aid me in my attempts?
