LD and concept of time

I read quite a few posts where people mention their dreams lasting 30 seconds, 5 minutes, 20 minutes... etc.

Is our perseption of time in "dreamland" equal to that in waking life? Do we THINK we had a 30 second LD or did we REALLY spend 30 seconds ludid dreaming?

I know it makes no difference in reality, I guess - if it felt like 20 minutes, then it was 20 minutes for that individual. I just think that a whole lot could be done in just 5 minutes of solid lucid dreaming - things not possible in "real time". But 20 minutes??!! I could only fantasize of such a wonderful thing!
:dreaming:

I here you Tornadoe Joe.
I have questioned people who claim their LDs last an hour -1/2 hour. But who am I to really question it. Ithink just because mine last 5 minutes at the most (or so it seems) it is probably envy. Yes the devil made me do it. :P

Actually Stephen LaBerge did an experiment on this subject and it was proven that the time spent lucid dreaming equals time spent in real life.
