You idiot, do it at night and you'll see. Just do it in your room, when your about to sleep, just do it.
Are you crazy ? These things never happen its all non-sense. Do you believe in these things ? Try it yourself and I guarantee you nothing will happen. I tried it at night itself nothing happened. The only time it will happen is when you are already fearful and you do it even if it has not you feel like it has appeared.
