A strange awakening

Last night was utterly ordinary. Nothing strange at all.Marty and I went to bed around ten and watched a bit of TV. We turned the TV off around eleven and settled in for sleep. At precisely 12:05, I was awakened by someone standing behind me and shaking my arm.I opened my eyes and looked over my shoulder, expecting to see one of the kids. But no one was there! And this thing had been shaking me hard enough to shake the bed.Once I realized what had just happened, my first reaction was to dive for Marty's side of the bed while loudly whispering Marty! Marty! Of course, he was sound asleep. So were the two dogs at the foot of the bed. Was I dreaming? Nope! No way! I could still feel the hand on my arm!! I curled up beside Marty. Wait! Not happening! My back is now to the door, and that is one high level of creep factor I have going on. So I turn over, put my back to Marty and snuggle in.I lay there thinking about what had just happened.........If this thing can actually shake me awake, what else can it do?. OK. I'm awake now......should not be thinking that at all..........going to be a long, long night.
