Sleeping with Mr. No-body

It was 3 in the morning, and I felt a presence climb into bed with me.  Asleep, I couldn't awake to check on my nocturnal visitor.  My eyes closed, but part of my senses alert I felt pressure along my spine, like that of a finger pressing and moving along my back.  I believe the presence was male, it whispered into my ear something unintelligible not unlike the nonspeaking adults in a Charlie Brown cartoon, "&%$!" was all I could make out, except for the very clear enunciation of the word, "blood."  Was my visitor seeking my blood?  Suddenly it rose from my bed, walked to my bathroom and relieved itself.  At least, I could hear what sounded like a male peeing.  I finally woke up, grabbed my bible and stayed awake for two hours.  I didn't see anyone, or feel my visitor anymore.  Oh, he's been back, several times, always in the early morning hours.  What does he want, I don't know.  But I do know this, he can get the heck out of my bed.  It's been a minute since I've had male attention, but I don't need Mr. No-body harassing me nightly.  What he offers, i can handle on my own.
