Mysterious happenings

Ok, so here's what has just happened...

I was at the steps of my apartment building, and suddenly I heard what sounded like a cat crying (it sounded like "no" but with an m)... after about half a dozen cries, it started to sound more like "hello" and then "help"... it got louder, and then just stopped.

I don't believe in ghosts, per se. I think that there is a lot that we can't explain with science. I also think that the mind is powerful and mysterious enough to create waking images and sounds.
The sounds I heard were more than likely a cat, or even a small child making mischief...

Nonetheless, I will NOT watch Ju-on or Ringu tonight...
