Thread: How can you have LD longer than 1 hour?

Sorry, the title of this thread was meant to say "longer than 1.5 hours".

Ok, so I've just joined and I was searching the forums for "longest lucid dreams" and found a few threads.
What confused me is that some members were responding that they have had LDs that lasted several hours.

Correct me if I'm wrong, but aren't dreams occuring during the REM cycle? ...and since we sleep in 1.5 hour intervals with the REM stage getting progressively longer through the night, the longest possible REM stage would have to be less than 1.5 hours, right?

How is it possible for someone to be having lucid dreams for longer then 1.5 hours, when our minds aren't even capable of sustaining continuous REM sleep for any longer than this?

Is it a perceived time? Did it feel like longer than 1.5 hours, but in reality, it wasn't really that long?
