Thinking it over, I've never been able to conceive of an obvious benefit to it, other than as a means to avoid bad dreams. But beyond that, why bother? What kind of absurd escapism is this? And then, just to wake up to a piss-poor reality, where I'd rather be asleep? Feh!
In the long run, I found that my diet had a strong relationship with the bad dreams I was having, and after I got out of college, and started buying food with my own money, when I purchased the foods I actually felt hungry for, instead of just raiding the refidgerator for whatever my parents had stocked with (or otherwise resorting to fast food), that bad dreams disappeared, and now I rarely have memorable dreams.
Sleep is restful and uneventful, when I get enough of it, and I'm thankful for that.
