Hello. Today I had a really strange experience in my dream. I was dreaming that my friend got in a fight with a horrible creature (I couldn't see them, but I heard). At one point I was going to help him (I felt like this situation supposed to test my courage), but then I resisted and stooped, because I felt scared and logically thought that my appearance will not change anything and I can't do anything to protect him. But the strange moment was that on some level I knew this isn't real situation (I haven't thought about dreaming), because I thought "if I can't help him in this 'dimension', I will not help him in the reality". So why didn't I start lucid dreaming and didn't go to help him? Maybe I was scared because I thought if something happens to me in this 'dimension' the same will happen in the reality. Can someone explain? And what this part of my dream could tell me about myself?
Also, in my dreams I often dream people from my life. How to interpret them appearing?
