White Puff of Smoke:
 
Here's another one for you...
 
It was early one morning, and I was preparing to go outside and water my plants when I remembered my ciggs at my computer, and while heading that way, noticed I was being followed by a "little puff of smoke." I thought it at first to be a ball of hair or something of the sort, for I have 3 cats. But it didn't float down--it FOLLOWED me. It even stood it's ground when I turned to face it--I sensed nothing bad from it, but I was very curious about it. The little puff just stood there for a couple of seconds--then, "poof" disappeared.
 
The next day/morning, I was still in bed, and noticed a little light floating by my ceiling. I rubbed my eyes--but it was still there! It was still dark out, and all my windows were closed-so no outside light it could've been. [Here in P.R. the windows are made of metal, so the room gets totally dark]. It floated there for a while, then disappeared.
 
I asked some friends about it, and they all mentioned an "Elemental" or "House Spirit." All good with me, I felt no evil from it. If you may have another explanation for it, or had something similar happen to you, please e-mail me about it.
