JMO that the Ilkley Moor alien photo is actually a man, perhaps on a bicycle, which would explain the short stature. Clearer blowups of the photo show buttons on his jacket and his left hand holding a large bag or something similar. He is looking to his right, two eyes are visible, a nose, mouth and ear. Perhaps a goatee and a hat. Also his right elbow is bent in the right spot and his arms are of normal length. No alien there.
As for the hypnotism issue, I went to a professional hypnotist who could not 'put me under' and gave up. Some time later, I had to go to the hospital for a procedure where I was under anesthesia - upon waking in the recovery room, my face was wet with tears and I had no memory of what had happened. While I was recovering, I watched a few movies, one of which was 'The Search For Bridey Murphy', a true story from the 1950's where a hypnotist puts a woman under and she recalls previous lives. At one point in the movie the hypnotist says, "When I snap my fingers you will remember something you've been hiding from yourself". Well, I suddenly remembered what happened when I was in the hospital unconconscious from the anesthesia when that man in the movie snapped his fingers, instantly. If you had asked me if I believed in hypnotism before that, I would have said of course not - but the fact is, it does work, at least it did for me.
Don't know about that police officer on the Ilkley Moor that day, perhaps he was abducted. JMO hypnotism simply opens the mind and allows memory to come forward very clearly. Someone told me that hypnotism is like a curtain being opened and I agree, our minds have many levels.
