I just have a question to ask which i've just been wondering about.

How do we know for certain that we've had a lucid dream? I'm certain when i'm dreaming, but when i wake up, i'm not too sure. I think, "why did I do that?" and "why didn't I remember to do this" and just overall it seems like just another dream after a while (except I knew I was dreaming).

How do we know that we actually were lucid and it wasn't just our minds tricking us? What if it is our dream persona who is thinking "i'm dreaming" rather than us and doing what we've planned to do before when we become lucid?

Before I was lucid, I was still doing different things to real life (deciding to appear in my room and stuff rather than walking the whole way). Then when I realised I was lucid I just began trying to do stuff i've wanted to do the next time I was lucid.

Hopefully that all made sense What do you all think?
