Right, exactly. I also think a good chunk of it has to do with things like false memories. You may only dream a few minutes, but you get false memories to fill in the gaps to make it seem like an hour. Let’s say you cross the street. You may just jump from one side to the other but you have the memory of crossing it.
Of course, that only accounts for some of them. I mean, I’m sure most LD’s that last so long aren’t mainly comprised of FM, so there had to be something more to it.
Thank you all for your replies! 
Has anyone tried WritersCube’s Dream Clock Theory yet???
Every other time such topic appears, I get a dejavu of having read about writerscube 
before…
I think the part where we fill in the gaps with false memories, makes most sense to me…I have felt in some dreams that I experienced the journey to some distant land(or a different place) while I am left with no memory of it…Now feeling that I must have travelled to that place highly influences my sense of time and thereby makes me feel that the dream was pretty long…I know its an awesome feeling that I made the most of my dream time, but I believe Laberge was right on this one…Of course you may blame it on my dream recall, but I would strongly reason it with false memory based mostly on the feeling…
For what its worth, dreams are entirely subjective and there’s not much to discuss on the sense of time when its totally your judgment that counts…
ive had limited experience but i found if i looked at a clock or counted in my head i could make time move slower. i could actually slow down the action of everything too by counting slower.
Any one know any more methods to do it? 
Well, what Im going to do is freeze time next LD, fot the sake of this experiment and well…
