This just now happened. I was standing next to my hall sink thats not really IN the bathroom. Aneways, I was just standing there when I began to fell this chilling draft of air from behind, and it was fairly warm in the room, along with the house. I turned and began to feel around the area to see if I could find a souarce to the draft. The vents weren't going on. I checked to make sure I wasn't getting the draft from my fan in my room that was on, but that wasn't it. I went into my ctual bathroom and felt around, but all was warm. I went back to that first area where i felt the cold and it was still cold. i stuck my head into my colset that has sliding doors--it was open and its not a deep closet at all. It was warm in the closet. Soon, I figured out, it was just cold in the one patch spot with no logical, scientific reason. It was a cold that tingled you all over and makes hair stand up type deal. Really freaky.
