Psychic and Paranormal
You asked if this could be a psychic attack? Yes it could, but I doubt it, when ever your attacked either in our physical reality or the supernatural one there usually is no doubt as to whether it was an attack or not. I do however like what Cat Whisprerer said about having to accept isness, I imagine that part of our work here is to learn how to accept messages that are beyond our capability to understand them. If you can first accept something then usually you are setting yourself up, or perhaps open, is a better word, to let your own abilities to learn from and come to understand the very confusing world of spirit, or multi dimensions, as Peter says, with in your own little universe that is you!
I look at the universe like a school and you get to pick just how and why it all works the way it does. It's your choice alone to build what works for you. If you can believe, that, then all things are possible depending on how you, or I or anyone else, actually perceives these things. I suspect that our universe or multi-verse is much more complex than we can even start to imagine at this point. Enjoy the ride, we're far from finished yet! LOL
