How long are your dreams ?. I'm convinced mine last between 10 - 60 seconds but from TV and films they suggest dreams can last hours maybe more .
Don't know...I'm usually too busy sleeping!
Not sure how long, but I wish they could be longer, I love my flying or hovering in the air dreams.
I have flash moments for dreams. Some a couple of seconds at a time. Never more then 5 seconds. Then theres a break in my dream were i analyze it like im remembering what i just saw or thought i heard and im still asleep. Ive woke myself up saying its just a dream.
Difficult to say without some monitoring device. Time is compressed with you are sleeping so it is very difficult to measure. You probably don’t remember all of your dreams. The best recent book on that subject is “Why We Sleep”, by Matthew Walker. This is a very good read.
