Looks like a duplicate of: [Why do dreams lose clarity quickly over time after we awaken?](https://psychology.stackexchange.com/q/7948/7001). Also note that dreaming is no longer associated with REM sleep. Evidence suggests that it happens throughout sleep, and the "REM = dreaming" hypothesis has long been abandoned.

@ArnonWeinberg To clarify, I was curious about the experience during a dream, in which time feels as it it passes and the relation to circumstances that would cause me to experience said dream, even if I quickly forget shortly after waking. If waking at a particular cycle of sleep (I suppose not necessarily REM) has a higher likelihood of dream 'recall' ie. having experienced a dream, wouldn't my experience of a dream be indicative of waking up shortly after?

@ArnonWeinberg Probability of dreaming is still highest in REM and lowest in deeper stages of slow-wave sleep, and the types/content of dreams differs. But yes indeed it's no longer the case that anyone thinks dreaming is *exclusive* to REM. People also report dreaming under anesthesia which does not have the same sort of organized state cycling.

Not sure about probability of dreaming, but certainly *recall* of dreams is both more frequent and more detailed during REM. As per the duplicate answer, this is because activity (arousal) of brain regions associated with memory is greater during REM.

@ArnonWeinberg I'm referring to experiments where the person is woken up and asked about their experience immediately prior, before it fades.

How are dreams "experienced" if recall is correlated with waking during a specific cycle of sleep (REM sleep)?

My understanding of dreams, from some basic research, seems to be that they occur during REM sleep and are likely forgotten unless waking happens during REM sleep, which is correlated with dream recall. The mechanism for this is related to the inhibition of long-term memory storage. This seems fine, but what bothered me was that during dreams I felt as if I was experiencing them in 'real-time'. Events in my dreams followed each other chronologically, I 'know' what happened in the past, and I felt like I had no awareness of future events in my dream during the dream. Of course, immediately after waking, I could still recall the events that happened, but this is after having 'experienced' all of the events.

This is puzzling to me because that seems like it would mean that my 'experience' of dreaming would somehow predict my waking: since if I wasn't about to wake up, I would have no recollection of my dream.

I came to two possible explanations for this (that at least seemed plausible to me, although being not highly versed in the field of neuroscience, the actual explanation could completely different):

1. The 'experience' of the dream happens in the moments of waking. When I am dreaming, I am not experiencing them as they form, but rather they are 'replayed' after already having been formed in the seconds of waking, but not yet being fully awake.
2. I am 'experiencing' the dream as it happens, but my brain forgets it unless I wake up shortly after. This means that I've also 'experienced' the dreams that I did not remember, they simply were not stored in long-term memory due to still being asleep. Wakefulness prevents the mechanism that causes me to forget the dream.

If 1 is true, then that would mean that some form of 'time-dilation' is happening in my mind. I 'feel' as if dreams last for at least some minutes, but that experience would have to fit in the span of seconds for 1 to be true.

If 2 is true, then to me it still doesn't resolve the issue of 'predicting' wakefulness.
