Early A.M.

Hey all, I'm not so new to this stuff but still have a lot to learn. Recently I have had something happening in my house that puzzles me a bit. My sister and I moved into a big old house a few months ago. Basically, she has the downstairs and I have the upstairs. I love the house and get a really good feeling being there. There doesn't seem to be any negativity hanging around. However, a week or so after moving in, I found myself waking up between 2:30 and 3:30 a.m. At least 5 out of seven nights a week. And its not my usual sleepy wake up, it's like I'm in bed and then all of a sudden my eyes are wide open and I am very alert. Like I said before, I don't feel anything bad but I do feel something. I usually have the feeling for about a half hour or so and then am able to fall back asleep comfortably. This happening for about a month and a half.

Then my dog, who had been sleeping downstairs with my sister and her dog all this time started sleeping upstairs with me in my bed and I noticed for about a week I slept through the night. After that, in the past 2 weeks, I've noticed my dog and are both waking up at the same time (between 2:30 and 3:30 a.m.) very alert. She's very protective of me, but I notice she doesn't growl, just alert, then she jumps out of bed, goes down the hall into what has been modified into the upstairs kitchen and stays there until I call her back to bed. Then we go back to sleep. I am not creeped out or scared by this, but I am intrigued as it's not something I have experienced before. Usually I am a great sleeper, as I love to see what my dreams have in store for me, so this seems unusual, as does the repetition of the timing pattern and my dog seeming to notice as well. I'm thinking it maybe a residual haunting that I'm picking up the energy too? I'm not sure... Any insight or advice would be helpful. Thanks:)
