The concept of Lucid Dream time

[h1nchm4n]

So, sometimes, you have very long dreams, and others, very short. For instance, last night I had a dream that lasted years. I woke up, and was shocked a dream could "last that long." See it here. There have been times when I've had dreams that lasted no more than 5 minutes. Yet, still, the same amount of sleep. Does this happen to anyone else? Whether it be very long drawn out dreams, or short, minuscule dreams? I would really like to conduct a case-study on this, if it hasn't already been done. I haven't done any prior research yet, this is just something I pulled out of my head. For this, I think I would like to get a group of dreamers, from completely inexperienced, to very experienced, to keep a dream journal for a month. They would journal like they normally would. And try to get a grasp of "how long" their dream was, and write that in the journal as well. Of course, dream recall will have an effect on how "long" you perceive a dream to be. This is why the group would compose of dreamers with varying experience. They would also have to keep some things constant, which I state below. I tend to have a very constant sleep schedule, and I'd say I'm pretty experienced with dreaming, but my recall is an on and off thing. This is also why I'd like to gather a group of dreamers to accomplish this task. Say you are running a normal sleep schedule. You get the same amount of sleep. You sleep at the same times. You don't take any substances or supplements to effect your dreams (or you keep them constant.) You are able to stabilize your dream for the whole night and you get the same amount of REM cycles, as well as similar length of REM cycles. Shouldn't the amount of "time" you have in your dreams remain the same? Is the concept of "time" in dreams a changing variable? Or is it something that can be calculated? Is it something you can change yourself? Or is it purely something your unconscious uses to limit itself? In the end of the study, hopefully, we will be able to determine what has an effect on the concept of time, in dreams. I'd like to hear some thought on this.
