About an hour drive away from me there is a retreat center that used to be an old nunery.  As a teen I was involved with a youth retreat at this particular center which is known to be haunted by some of the old nuns that died there.  One night during the middle of the night I got up to go to the bathroom and on my way back to bed I saw 2 fuzzy figures standing at the top of the stairs near the chapel, and when I turned back thinking my eyes might have been playing tricks on me, I felt a cold hand on my shoulder and there was noone else around.  Freaked me out!
