Body/emotion taking me out of meditative state?

I'm really sorry for the late response, I've been studying like crazy for my finals these past few days.

Hm, I don't think it's you, well, probably not, at least. But it could be that you were able to leave the body.

Let's say for an example, you were floating few inches above your body, usually if you're scared before you project, once you get out of your body, you'll be 10 times more scared.Even sometimes when people are not afraid to project, once they get out they'll suddenly get frightened, that is because your body really doesn't want you to go anywhere.

So in your case if you got out, it could be your mind messing up with you, otherwise I believe that it might be some entity targeting you, since you said dogs would bark frantically around you. Animals can sense paranormal activity very well, especially dogs and cats, so having a lot of dogs acting weird around you for no reason at all is really eerie.

I Hope you stopped having scary experiences at this point.

Best of luck!
