Time changing... so one of you is arguing time cannot change just the perception of time can. The other one is arguing that the perception of time is the only evidence of time we have ever had... fun fun.

Not here to argue, just to share my opinion.

In lucid dreams it seems like my perception of time is about the same as real time. Going from alarms that go off and another experiment I won't go into.

But in real dreams you will often dream that weeks will go by. I think that it doesn't matter if you perceive weeks or if it actually is weeks. What you perceive is all that matters and if you can perceive time taking longer in a lucid dream then that is Boss.

I once had a dream that I had a childhood friend. This dream inserted memories throughout my entire life, changing my childhood. seeming to take a long time, but seeming like it only was me remembering it. I woke up and started being afraid that it had all been a dream. I found her sleeping on my couch and I was relieved. I then woke up for real and knew that she was gone.

I don't know how to change the time in a dream. But you can think about tons of different memories at one moment, just think of a friend and you will have dozens of memories pop up. If you try to remember fake things in your dream wouldn't they pop up as well? You might just seem to remember the things and not actually dream through it, but after that it just goes to a memory anyways and it will get mixed in with the dream.
