+1 on spaces. Very true for some reason.
I mostly read a few books on the matter, kept a dream journal, and woke up after 5-6 hours of sleep for a half hour then went back to sleep. The best distillation of how to do it came from https://www.amazon.com/Learn-Lucid-Dream-Techniques-Consciousness-ebook/dp/B07Y2FS6CY/ref=sr_1_24?dchild=1&keywords=lucid+dreaming&qid=1630302371&sr=8-24
There's a personal anecdote in the book that is very similar to a glimpsing practice during a dream. Highly recommend checking it out.
Thank you! And from the .com version of amazon - https://www.amazon.com/Shift-into-Freedom-Open-Hearted-Awareness-ebook/dp/B013RLHMW2/ - for us Americans, also 99 cents right now.
