When one is out-of-body the physical world is seen in a fuzzy haze, like a mild fog. But the spiritual world – deceased relatives and such are clear. If the letters were large enough I think they could be read. I know of the experiments with signs around the ER, these have not been seen by an experiencer. I am not surprised, the concentration is on the dead body and what is being done to it or worry about relatives. The last thing would be to look around the building to read the signs.
There are multiple ways to know you are out-of-body. You can move easily from room to room through walls and ceilings, some are documented to have traveled great distances from their dead body. Danion Brinkley followed the ambulance carrying his body to the hospital. You are not able to touch things or make people still living in the physical hear you. Many NDEers have tried to grab their relatives and tell them they are ok, but couldn’t do it. You notice you don’t have a body, but are “wearing” a white gown. That is really energy. This happens before you see the light.
In the light, radiant glowing golden light that is conscious of you, most feel this is our creator or God. In the light is love so strong and so accepting that you never want to leave. There is also knowledge of all things. You know who you are and what you are doing here, how the world was set up and anything else you want to know. Thoughts are the key, Think of a question and the answer is there. Think of a location and you are there. This is why NDEers says thoughts and love are everything. We are here to learn about our thought processes.
I will stop, probably said more than you wanted.
But will be happy to answer more questions if you want.
Love
Seriously, I’m making the point that your feelings of whether evidence is “extraordinary” or “impressive” have no bearing on the truth value of the claims, or the worth of the evidence.
