You may think its paranoia, but after watching 'The Exorcism of Emily Rose' and finding out about the witching hour (3am-4am) I have always hated being awake at that time. There are e few examples of things that have happened. The first was when my daughter was about a year old and woke to have a bottle. It was just after 3am and I decided to sit in the lounge with her, because it was nice and warm. Everyone is sound asleep when I hear a child crying and a man's voice comforting them. I assume it's my 4 year old daughter and my husband trying to get her back to sleep. It's not very loud and as I'm taking my other one back to bed, walking down the hallway the noises fade and then stop. All our bedrooms are pretty close together and I look in my daughter's room and she is sound asleep. I look in my room and my husband is sound asleep also.
Because it had stopped when I was just outside her door, I would have seen one of them up? When I asked in the morning, he had said he slept all night. A few days later I saw a boy smiling in my daughter's window.
Also, my 4 year old wakes at 3 sometimes screaming and fighting something and it takes a few minutes to snap her out of it. Sometimes I even wake up after 3 because it sounds like a TV has been turned on with the volume right up and I hear a man talking so loud it gives me a fright, but after a few seconds it fades and disappears. I don't think it would be a spirit that knows me, because surely I would get a nice feeling rather than a scared one?
The last thing on this is, my brother came to stay and heard my now 2 and a half year old at 3am saying 'stop laughing at me' alone in her room before calling out for me to come get her.
