Lucid dream about my childhood

Well i'm 18, and last night I found myself dreaming about when I was 11. I know I got all the facts wrong in the dream (was set in winter, when it should have been set in the summer), but I dreamt about becoming/retaining my friendship with my best friend at the time rather than letting it fall apart. We are/were both known to hold grudges lol, you didn't want to get on our bad side or you would stay on it. I believe I got this from my grandmother, but it doesn't really matter. What i'm wondering is why did this lucid dream happen so randomly? I haven't even thought about my buddy from my childhood in years, now today/last night just random lucid dream where I went around for a couple months. Following my childhood, but constantly doing this to repair my friendship with him...any suggestions or thoughts on this?

Side note: I haven't really dreamt much in the last few years to be honest, probably due to not sleeping enough, althou often my dreams will just get started when I wake up. Hope any of this helps with helping me...just trying to find out why this random dream came around.

Quite often we may dream of a different time in our dreams. Our memories of old and new get mixed together. Things that have left an emotional trace may come up more often. For that matter, I also dream quite often of my schoolmates, even though I haven't seen them for years.

*Moved to dream interpretation*

When you say "lucid dream" do you mean that you were consciously aware that this was a dream and controlling it, or do you mean at this dream was vivid? For the purposes of this site we do not use lucid and vivid interchangably, although I know that a lot of people who are not in the lucid dreaming hobby do use them as synonyms. For interpreting your dream, it could make a great difference to know whether this dream was brought about by your subconscious entirely or whether you were consciously controlling your dream.

If this was a lucid dream during which you were aware it is a dream and somewhat in control, then I would ask you what your expectations were at this point in this dream, what were you trying to accomplish when your childhood buddy showed up? This could provide a clue to why.

Otherwise, can you give us as many other details as you can remember about this dream, dream interpretation of one dream element like this is nearly impossible without any context, I believe. Ideally we would also know a bit about what is on your mind currently, what issues you are facing, whether anything nowadays might bring back memories from before for you - do you see any connection between your current situation and your childhood, when you think of this childhood friend does the friend represent something for you - what qualities made this person special, what was this friend especially good at or known for, and is there anything nowadays that you can think of that might tie in to that?
