Could we log the types of seeing in dreams and use some as dreamsigns?

At the moment I'm thinking that types of seeing could be considered to be dreamsigns, rather than the things we actually see. Here are some types of seeing I'm playing with as possible "seeing/looking dreamsigns".

Something moves closer and closer to my face.
I follow something.
I see something through glass.
I switch my focus from near to the distance. (and vice versa).
I see blurriness when under water.

Regarding the "Something moves closer to my face", I'm thinking that could be a good one because the eyeballs have to go cross-eyed when an object moves close to your face which I think may cause the sleeping eyes in the real body to be stimulated in some way.

What do you think?

I like the idea! I have also noticed different types of seeing before (some of them mentioned above).
I would like to add shifting focus between two different events quickly (sort of like a split-second of a blackout between two different events you focus on). Also the "seeing through glass" sounds like a good dreamsign to me.

Thanks Benni. I will have a tinker with the idea and see what I come up with.

Great! Please keep me updated.
