I am often scared to go to bed, too. Here are some things that help me: leaving various lights in the house on, so that nothing is completely dark; making sure I don't go up to bed until I'm at least a little sleepy (and I use meds to get me that way); watching a familiar movie or tv show on tv or my computer so that I'm not paying close attention to it but the noise distracts me; and turning it off early so I can sleep.

Being scared at night stinks.
