Recently I enjoyed the movie Lucid (2018). “Zel, a lonely young man’s life changes when his enigmatic neighbour offers to help him overcome social anxiety.”
I have quibbles with it – e.g. I wish they had gone into more precise detail on reality checks – but I liked that it dealt fairly realistically with lucid dreaming, and portrayed it as producing psychological growth if approached in the right way.
