I know there are different views when it comes to OBE/Astral Projection and Lucid Dreaming....I think people can be influenced by their beliefs what happens after death, this question can have a big impact.

But if lucid dreaming is all just in your own head/mind, how do you explain accounts where people have organised to meet at a certain location one night and then then they come back and can describe the same conversation they had there/the things they did etc.?

Robert Monroe did a lot of experiments like this at his institute which involved multiple people going to the same places, talking to different deceased people etc. and having the same experiences that seem to suggest something a lot more than subjective experiences.

I just think it is all very interesting
