I believe I have posted before about strange things that happen - odd smells, the feeling of someone touching my hair, feeling of someone touching me through the bedclothes, or just the bedclothes twitching a bit for no reason.
The other day DH (who is not really a believer, but has experienced some of the smells) saw an orb in the living room. He described it as like a laser pointer, but white, not red. He tried to explain it away by saying it must have been a reflection of the TV that was on.
Also things get lost and wind up in odd places. The last was a spoon I had been missing. Wound up in a canister of flour, spoon end up, can't figure that one out. If I had put it in there, it would have been spoon end down.
