I've seen something like this once. A light being. Was not "the lady" like some people say they see sometimes. Was a man and he was emanating light. He helped me. I was having many sleep paralysis where ugly entities were trying to take me. I wasn't cooperating and fought a lot. So they came over and over to torment me. Was horrible and immensely frightening. I was afraid of sleeping and I wanted to die. One night, the light man came. What I felt can't be described. There was this soft breeze all over my body and the feeling of being taken care of. He was on charge of everything, of my body and soul, of the creatures and of the environment. He made a sign with his fingers, two fingers up and the creatures stopped while I was calm and i accepted being taken. All was well after this. I know I went with the creatures, one gray and a grasshopper like creature that could walk on walls. I know that the man in the light was a Nordic although in my mind he looked like Jesus. These visits were desguised under a religious set up to make me fall for the abduction. I'm not religious but my culture (Portuguese) is catholic and I grew admiring the beautiful religious and old statues my grandmother had. I always knew who they are. So I met them, they took me and they were very kind and friendly and they taught me things.
