Nightmares

I really and truly believe that Bradley is having nightmares a lot lately. Sometimes when he has been sleeping for a little while he will all of a sudden cry for about 2 seconds and then stop. By the time I get into his room he is all peaceful again. This morning he had fallen asleep eating and since I was really into my book I decided to let him lay by me for a bit. He got the saddest face and starts whimpering and so I try to wake him up. He wont actually wake up but I think he calms down with me talking to him but his breathing is funny for a couple minutes afterwards like he had been crying really hard and is still trying to relax. I don't know what he would be dreaming about that would make him that upset though. We don't let him just cry when he is upset, he doesn't go hungry, and he is a happy baby when he is awake. Just last night before bed Scott was making him laugh harder than I have ever heard before. I thought when it happened on vacation it was just unfamiliar surroundings and that the room was darker than he is used to but now it is happening at home too. At least he seems completely fine after waking up and doesn't seem to remember a thing.
