Some theories about the black cat apparition

This is by no means a comprehensive list of what the black cat apparition might be:
1) It was a Thought-Form created by my Mind. Somehow I had accidentally discovered for myself the Tibetian secret of creating a Thought-Form
2) It was an animal(cat) ghost or spirit
3) It was an entity from another dimension
4) It was some other spirit or entity disguised as a cat spirit (maybe because it wanted to tease me for fun)
5) It was a hallucination

Theory 1) is possible because not too long ago (perhaps some days ago before the appearance of the apparition) I remember myself drawing a cat that looked something like what I saw. I cannot recall whether at that time (prior to seeing the black cat apparition) I had read any children's book on ghosts and other scary paranormal phenomena.

I doubt very much that Theory 5) is true. I don't know how the experience of having a hallucination is actually like. Without having constant hallucinations, how am I to know what the experience is actually like?

Without a doubt, I had experienced something that night I had never before experienced and it was something extraordinary.
