Silk Cut, you said it happened many years ago and then you said it happened last Thursday, right?
Well, usually this kind of thing occurs with a young person, teenager, which I imagine you were years ago. It`s probably some kind of kinetic energy that is associated with the time of puberty, and females. If the energy is strong enough poltergeist phenomena can occur. Although these things usually die out as the person matures so why it should be happening now, to you after many years, is interesting.
