Things that Go Bump in the Night

I'm starting to understand why there have been so many children's books written addressing monsters in the closet, under the bed, etc.  A couple nights this week Neal has found Emily asleep on the couch after I'd gotten up and put her back in bed.  Then last night she got up in the middle of the night (again) and when I put her back on bed she grabbed a hold of me like a baby possum grabs its mama and she wasnt about to let go.  "It scare me"  "What scares you?"  "It" and she points around trying to find something to point at.  Up until this point I was convinced she was "scared" because she wanted to come sleep in our bed.  But this wasnt pretend scared, something was really scaring her so I told her I'd lay with her a few minutes.  Then we heard a noise and she held on to me even tighter.  Hmmm...why  is the water running downstairs causing the pipes to make noise??  Was very short, but evidently plumbing noises are very scary.  Today I figured out our downstairs toilet is running every so often, which would explain the intermittent noises.  Didnt have time for toilet repair in my schedule though so tonight, the water to the downstairs toilet is shut off, so hopefully I won't be up at one am singing "God is bigger than the boogie man" to a 2 1/2 year old that is scared of her bed and will only sleep either in my bed or on the couch.
