I have a friend who has a large house out in the countryside. About a month ago he invited a bunch of friends over for dinner (pizza and Dr. Pepper) and also invited everyone to spend the night as it was late and it's way out in the countryside. I woke up in the middle of the night, the curtains were moving and I saw the shape of a human behind one of the curtains and although "it" didn't actually speak to me, I felt as it if was trying to tell me something. Now, I don't believe in ghosts but I just want to make sure I understand the scientific method. Something has to be repeatable, right? The next morning at breakfast several other people mentioned not sleeping well and hearing strange noises and some of them saw the curtains moving just as I had. I don't pretend to know what was going on, but I do believe that we don't know everything and I'm just asking you guys if I might have seen a ghost and if science, though the scientific method, might not agree in this particular case?
