A 14 month old girl wakes up about 3 a.m. sometimes screaming bloody murder or just all of a sudden sitting up in bed and watching the ceiling like she sees something. It's spooky. Cats do that sometimes. She is such a lovely baby and a happy baby. This has been going on for a couple of weeks. One time she was screaming eyes wide open and holding her arms straight up. It freaks me out. Is this normal?
Given your description, it is not paranormal, it is NORMAL :)
These are called night terrors, which children in that age have, and they are perfectly normal. You may still want to check this out with your pediatrician, since the normal age for night terrors to develop is 3 years old+ (though children as young as 6 mos. can also have them).
If you want to understand more about night terrors, google it. Here are some samples I found:
