a quote from "exploring the world of lucid dreaming" of Stephen Laberge:

"I knew that earlier studies had demonstrated that the direction of dreamers’ physical eye movements during REM was sometimes exactly the same as the direction that they reported looking in their dreams"

...

"One of the earliest experiments conducted by my research team tested the traditional notion that the experience of dream time is somehow different from time in the waking world. We approached the problem of dream time by asking subjects to make an eye movement signal in their lucid dreams, estimate a ten-second interval (by counting one thousand and one, one thousand and two, etc. ), and then make another eye movement signal. In all cases, we found time estimates made in lucid dreams were within a few seconds of estimates made in the waking state and likewise quite close to the actual time between signals. From this we have concluded that in lucid dreams, estimated dream time is very nearly equal to clock time; that is, it takes just as long to do something in a dream as it does to actually do it."

i think that answers your question
