I have heard from some people that while you are in a lucid dream you can talk to other people you know who are dreaming and you will both be in the same dream together. It's hard to explain but basically you would both be able to recall the events in the dream you shared.

I also heard that a person can have a "precognitive dream" in which they can see the future to a certain extent, and that this is kind of what happens when someone who doesn't experience lucid dreams has deja vu. But if it is lucid you will know what is going to happen (little things and stuff).

I don't currently have lucid dreams because I only found out how to get them today and I still need to start working on my dream recalling.

Can somebody tell me something about the truth of these statements, maybe share an experience like I described?
