In the past I have had experiences seeing crafts hovering over my home before and taking my sister and I. I have in the past seen entities entering my bedroom and taking me with them. However, last night I have no memory except for not remembering going to sleep and waking up extremely drowsy like I had been drugged. I remember this sensation from previous experiences. When I woke up I opened my door and noticed foot prints that appeared from the middle of the yard where a bi-pedal entity walked towards my door and the prints stop at my door step. There are no return prints. I have included several photographs. I would really like to know what left behind these very strange prints. Whoever left them was heavier than myself as far as I know because the prints pierced the snow into the ground. This is the first report I've ever made of any of my experiences. I've never actually seen evidence left behind before after any of them. For comparison I imprinted my own foot about 4 inches to the side of it and it appears to be about 11 inches long. Thank you very much for your time, I apologize I do not have further information to give you on this incident.
