I've had similar experiences, and (having studied neuroscience as an undergrad and in casual / amateur research in the many years since) feel there's a lot of untapped potential to leverage in our hypnopompic and hypnogogic states (at the fuzzy boundaries of sleeping / wakefulness). Fascinating stuff.

Also, please forgive my question which may seem impolite but I really want to know: why did you type "whilst" instead of "when" or "while"? Have you ever said the word "whilst" out loud, in a normal conversation? More letters, an extra (half)syllable, zero meaning or nuance added, I just don't get it. I wonder this every time I see it, mean no disrespect and would be grateful for a straightforward reply. (/tangent)
