Just read that the average person spends about 6 years of their life dreaming

I was looking up random sleep facts online yesterday and saw that stat. It came from a university study I found linked in a science blog. They said if you live to 75, and dream for 2 hours a night, it adds up to that crazy total. I always thought dreaming was just a small part of sleep, not years worth. It made me wonder what we're actually doing with all that dream time. Has anyone else stumbled on a fact that made a normal thing seem huge like that?

Honestly that six year number got me looking up how they even track dream time. Tbh the real mind-blower for me was learning we forget like 95% of our dreams within minutes of waking up. So we're basically spending years of our lives building these detailed worlds and stories that just vanish. Makes you wonder if that lost dream time is our brain's biggest waste or its most important work.

That 2 hours a night average feels high to me. I've read most dreams happen during REM sleep, which only makes up like a quarter of your night. So six years seems like a stretch unless you're counting every single sleep cycle.

I remember reading a study from UC Berkeley a few years back that looked at dream recall and creativity. @sean_foster52 you're right that most dreams happen in REM, but the 2 hour average actually lines up if you factor in how REM cycles get longer as the night goes on. The part nobody talks about is what they call "micro dreams" during the other sleep stages. There's some newer research suggesting we have dream like brain activity even in deep sleep, it just doesn't have that same narrative structure. So the six years might actually be on the low side once they start counting those fragments. But your mileage may vary, I'm just a guy who reads too many sleep articles at 2 AM.
