Hello everyone,
I’ve found this forum by chance while looking for some information about “remembering one’s day everyday”. After reading about people with hypermnesia and about memory techniques in a psychology course, I thought it should indeed be possible to remember one’s days in details if enough attention and effort is put into it.
What I’ve started doing is a bit different from what is described here, but close enough so that I can ask my questions here I believe. A few days ago I started to spend about half an hour every evening, just before falling asleep, remembering the details of my day, and pinning it to my mental calendar (which I have always had for important dates). I’ve been amazed to realize that most of my day was still there in the evening - that, if I wanted to, I could have spent hours living my day a second time with almost all of its details. After the day review I quickly check back the previous days to see that I can still remember the main events for each date.
The question I have is linked to sleep. I haven’t found any scientific publication about it, or any publication at all for that matter, and this is why I am asking it here because maybe some of you have had similar impressions and would like to share them.
Sleep and REM have been shown to be linked to sleep, and may be some kind of process by which the brain passes memories from the daily buffer to long term memory. What happens when I do these day reviews is that I do indeed get REM (though I’m not sleeping; but this is quite logical if you consider that I am looking at the landscape in my head, in the first person, a bit as if I was in a dream - I am actually looking at everything that was around me during the day, not remembering things through words). But then, after I finish my review, I feel quite nervous. I wonder if it is caused by the quite long intense focusing effort, or if it’s because I’ve “burdened” up my consciousness with too many images and thoughts (a bit like when you’re anxious because you’re thinking about ten things at a time).
Any way, I find it harder to fall asleep because of this nervous feeling (which is not very nice), but then surprisingly I’ve waken up earlier (without alarm clock), and with much more energy than usual. I tend to need about 9 hours of sleep in order to wake up spontaneously and feel that I’ve had enough rest, but in the past few days it was more about 7 hours 30 (which would generally make me quite tired the whole day, but not these days). Again, I don’t know whether this is linked to some other factors in my life or whether this has to do with the fact that the “memory consolidation” process has partly been done before actual sleep.
I know that I’m only starting this experiment and that only time will tell what effects are caused by the memory review, but I was wondering if any of you has experienced something similar. Also, because it made me feel nervous, I’ve considered dropping the experiment completely, thinking that maybe this was something not so healthy and that the purpose of sleep might be precisely to dump the non-important details and keep only the most important things available in memory, process against which I’m going with my experiment.
The idea of remembering only one image seems less challenging, and I will try that (one or a few images). But if any of you has something to share about feeling nervous after a few minutes of intense consolidation, or about the link with sleep, I’d be happy to read it !
