The obstacle I am talking about is a sentiment I have heard from many people, that dreams have insight and being lucid detracts from the dream. Someone that is lucid might disregard the dream and seek to fly and experience fantasies instead of letting the dream unfold naturally.

My dream is one dream but it is indeed one of many dreams in the school setting and although they are not stressful per se, I am constantly frustrated with being unable to accomplish nonsense tasks. That is why I am giving thought to this dream. There are many other dreams too that have this problem. For example not finding my way or looking long for something. That's why it's worth thinking about.

What can lucidity add? I think being lucid in these dreams is an asset because you can think this is a dream and the task is nonsense because of the unstable nature of dreaming so I need not try to do this homework. I did not fail to study, I only exist in this moment but I did not exist in the past of this scenario. Then I might choose to let the homework go on and listen to the lecture instead or I might try to talk to my peers or just do something else.

My point is non-lucidity leads to a cul de sac in a dream.

For example, once I dreamed I was driving and my passenger and half the car was gone. I almost panicked but a bit of lucidity informed me this was due to the nature of dreaming and I kept driving until they came back. This is an example of lucidity stabilizing the dream vs non lucidity spiralling dreams into nonsense frustration.

About waking up from dreams and just saying, "well, that was random and meaningless, let's move on"... Well, that's interesting. Isn't that a bit nihilistic? I do agree dreams have a lot of randomness but I do think they arise from real experiences and can be a reflection of my daily life so I do like to look at it as if I were looking at my reflection in the mirror to check that my face looks healthy and well kept. Others are looking for symbolic meaning, which I don't adhere to.

About your tree dream, I don't know what lucidity would have added either. Perhaps this is a dream others would look for symbolic meaning from and lucid, they might abandon it to go flying (losing the insight) and others might start asking it question (and I believe they would receive meaningless/expected/random answers). I think if I were lucid in that dream, I would just soak in the experience and let myself be in awe of the tree, for what that's worth.

I guess a follow up question would be, how do you redirect your focus when lucid.

Personally, it often disengages me from the current narrative, leaves me purposeless (without narrative), perhaves indecisive due to the infinity of options, powerful, in awe of the dream world, in fear of its ephemeral nature.

I think it's worth thinking about how those feelings (due to lucidity) affect the dreams (compared to those of non-lucidity, which on the other hand might lead me to feel confused, frustrated, powerless, etc)
