This is not a muscle spasm

There is nothing like a good night's sleep. At least from what I have heard. I wouldn't know personally, as I wake up at least four times a night. Usually it is from noises outside, or from my honey jumping around in bed. Last night, right before bed there was this noise which sounds exactly like someone walking around the apartment. And I dont' mean a little. I mean, it sounds precisely, exactly, positively, like a person walking around the apartment. I hear it about once or twice a week, and it is kind of spooky. So I happened to share this view with my honey, that it was not, as we had speculated, some odd sound trick created by someone walking upstairs, but was instead a ghost. Boy, you'd think some people really fear the undead, because just bringing it up made her all mad at me for scaring her. So anyway, we go to sleep, then about 3 am I feel a tapping on my head. So I wake up and ask her "what" as in "what do you want? Why are you tapping on my head and waking me up?" Only she is asleep. And my first thought is that she tapped on my head in her sleep, though I notice that the blanket is up around her chin and her arms are pinned below it. So I figure I imagined it, or dreamed it or something. And I try and fall asleep some more, but I'm laying there awake. And I feel it again. This is not a muscle spasm, this is the very clear sensation of a person tapping on your head. But all I have to do is open my eyes to see she is still sleeping, so I can only conclude the undead was tapping on my head. Which you might think is scary, but I figure if a dead person wants to tap on my head, I guess it's ok with me. As long as they don't kill me.
