Hi,
I have experienced several time dilated dreams, but like shared dreaming it's one of those things that can't be evaluated by individual study.
Giz is a very notable figure in the lucid dreaming community and he believes time dilation is impossible. What do you think? Have you experienced time dilated dreams? it doesn't have to be lucid.
I think the main problem with the current theory against time dilation is in assuming that all eye movements are translated to waking. Perhaps, only some are.
