I keep hving drems that I have died and I am amongst people who can't see me. Dreamed that last night for the second time this month. I know it is not an invisibility dreams because there are people who can see me and they are dead too.
Then I wake up and am like "Hmmmm?"
Just two thoughts come to my mind. I read once that everyone in your dream is an aspect of yourself. Can you pin down what the people in the dream represent to you? Maybe it's a fear of not being heard or listened to; or a fear of making a change, of being in a strange environment, cut off from the familiar.
The other thing is, if you believe in astral projection, maybe those are vestige memories of being out-of-body. They say everyone projects in their dreams but few have memories of it. The"dead" people are also out-of-body; that's why they can see you.
