Where are you on an astral journey / soul journey?

Hi, I just watched the "She Knows About You" series on Netflix. There's a lot about out of body travel. I've read up a bit on the internet on the subject, but I still don't understand some things.

On the one hand I ask myself what "world" you are in when you go on an out of body experience. Are you in the real world and can you follow all events? Example: A conversation that takes place while one is in the out of body experience. Or is it that you are in a dream world, so to speak?

Another question is, how is it possible to meet other people during the trip & why is it not possible to swap bodies.

Below you will find a survey on whether you have ever done an out of body experience.

I thank you in advance!

There's no such thing as astral beings…

There have been people who have seen their body from above during an operation.
