Personally, I find the subject of lucid dreams somewhat interesting but my best memory of such a thing was an infamous fanfiction piece called My Inner Life (which I don't recommend reading unless you're already plastered with some friends on the side and really got nothing better to do at night, although you could actually have it read to you on YouTube via a series of videos by the almighty mutant museum) but I do understand that the mind is able to generate dreams in a particular way assuming you direct it in a certain way. Although the level of induction is complicated, some have an easier time guiding it towards things they wish than others.

Oh, and for the record, most of my dreams were rather boring. No SHL dreams either, shockingly.
