I have had this too, also a lot of daydreaming as you described in another post. When I was in high-school when my DPDR started, I used to close my eyes during boring lectures and picture different things with the maximum level of details. I used to picture a long colored tunnel, with different branches, and traveling in the different branches as if I was in a flying spaceship. I also had a lot of sexual fantasies back then, and I would play them over and over with increasing level of details. This gave me a fuzzy feeling and made me a little numb. I remember I did enjoy it and it gave me intense feelings. But I learned with time that this was actually part of my problems, doing these things caused me to lose touche with reality a bit, imagine scenarios with girls that I thought were real but were not true, and I had many ideas both grandiose or depressed that made my life go up and down constantly with no particular connection with reality (everybody loves me, nobody loves me, that girl has a crush on me... for some of these things coming back to reality was sometimes very hard and made me depressed, it was a very hard time for me). Now I run away from these daydreams like the plague. I just want reality, real life. I do feel much better now and perhaps that change contributed to it. But just thinking again about that state of mind I had back then gives me the chills. For me, enjoying something that is not real, but imagining it is real, always comes with a price.
So I don't know if this is connected to DPDR but I did have a lot of daydreams that gave me fuzzy feelings.
But when asking other people if they have similar feelings as we have, there is the risk that they do have such things but don't even realize them. I think people with DPDR are much more analytical and can observe themselves much more and often do so. Sometimes I describe things to people that I know for a fact affect everyone, and they still don't know what I mean because they never paid attention to these things, which is often puzzling to me given how these things seem clear to me.
A recent example is that I bought these kind of glasses, a pseudoscope
and a hyperscope
, which are devices that mess with your perception of depth. I find them really cool and they immediately cause super strange and interesting effects for me. The thing is that our brains can get depth information both from perspective and from binocular vision. When you close one eye you will rely on perspective only, and with two eyes you add information from binocular vision, like difference in parallax or I don't know how it's called, and you get more information about depth. When you use these devices, they mess with parallax but not with perspective, so your brain knows something is wrong and tends to rely on perspective only to make sense of things, and so a lot of people will not even realize these devices are having any effect on their vision (especially with the pseudoscope). And when I showed them to my friends, most of them thought it was boring and could not see any difference, when for me I had to focus just a little to realize all these effects. Like with the pseudoscope for example, depth perception is reversed, what is closer seems farther and vice versa, so concave shapes look convex. It's pretty weird, but somehow most of them don't even see it or it's not really striking to them, even if I describe everything. And this happens to me very often, and this I think is more related to DPDR. I can be very aware of different perception stuff that nobody else will notice. A lot of people will just focus on the actual object they have in front of them, and never on the way they perceive things, unless some effect happens to them that makes it impossible for them not to notice.
I had the same with side effects from meds. I know someone who took the same as I did, and when I described some very minor effects on my perceptions (not bothering effects), he realized he had the same but only after I told him. But I could have made a whole list of things I had noticed. Like with some anti-psychotics, I had weird impressions of movements when I was reading, or I could be startled by my shadow moving when usually this kind of movement is automatically regarded as unimportant by the brain, I noticed some very subtle changes in my body perception in space (I would hit door frames sometimes), very subtle changes in my ability to articulate or to swallow my saliva. And I was not paying attention because these things made me anxious, they really didn't, but just because I am naturally drawn to look at my perceptions a lot. And I am pretty sure a lot of people who took the same meds at the same dosage would have no idea what I am talking about.
