I know what you mean, about the 'history' channel!

Just the other day I was mentioning to a friend that it had been a while since I remembered a dream. Well, sure enough, that night I 'remembered' being very busy the night before, when I woke up. I knew I had had several dreams, and an image was 'stuck' with me from the dreams. It was the back of a man, and was superimposed on the image of someone I know well, but I knew when I woke up that the images didn't 'match' and my mind 'stuck' with it until I figured out where the 'back of a man' image came from. It was an image from a news article I had read that day. So, the dream had another layer to it, something else I could look at, if I wanted to do that.
Speaking of dragons, I saw a picture of a snake with a foot recently. Dragons were mentioned in the caption of the picture, and my mind was actively creating a dragon out of the ordinary looking snake with a silly foot coming out of its side. Why do I mention it? Well, dragons are just not a usual subject of conversation in my world, not ordinarily.
So, standing next to Hitler. That could mean all sorts of things. I think it depends on the context, the larger picture of it all. Great for you if you can decipher it all, but maybe you get 'another chance' if it doesn't all come to the forefront immediately.
People who are alive joining in. Well, that must happen, too, all the time. Seems like Juditha just created a post about the same thing happening to her. All kinds of spirits, just making themselves visible, making themselves felt. Sometimes it may seem to be too much. In such cases, I can feel my ears closing (physically, really, lately) and my mind blocking off the dreams so I won't remember, so I can have some peace. I do think we have a choice, at least for periods of time, to skip the 'lessons' -- or just to do it in a way we don't remember. Kind of like sleeping on your books and waking up and knowing the answers. Like magic.
