Ever since I started studying the functions, I've always felt I was an Si user, consciously. I've been seriously considering the possibility of having it in my tertiary - I get nostalgic at times, even when recalling events that seemed melancholy. Sometimes I try to envision myself back into that environment internally - when I say environment, my state of mind, or what I was doing, or what was happening around me. It isn't strong enough to pay great attention to information, only when it strongly strikes me am I able to recall. Sometimes, when I look at situations that have happened in the past (usually non-related to me), I might think about what I was thinking about at the time, or even slight things like what kind of music I was into, my interests, etc. For example: when the James Holmes thing broke out everywhere last summer, one of the things that immediately comes to mind was the fact that I started talking to this girl that I liked, during that time period when the media was covering it. Instead of thinking "Heh. James is a douche. What a shame." or "The media talked about this an awful lot...".
But I've been considering Se lately - as my Pe function quite possibly - only based on how sometimes when I look at something, I might start noticing the details of the object itself, and describe them in my head (although this usually happens when I'm bored, and I tend to "force it", although I sometimes force possible Ne out as well), or when I'm eating, I don't usually abstract the taste into past sensations or experiences. Could this be a sign of a poorly developed Si?
Last but not least, here is a photo I am going to evaluate:
Apparently this is a tree surrounded by dense fog. You can't see anything else. The next time I looked at this photo, though, then I looked at it closer, and remembered when I was a kid I would pretend that gardens, small plants, weeds, shrubs, and other related things, were cities and towns. I implement that imaginary context into the current one, or abstract the bumpy-looking grass into a large urban sprawl, or a series of towns. Looking farther ahead, it looks like a tornado is touching down, or a lightning bolt is striking, so I abstract the branches into some dark storm cloud. Then, I realize you can't really see anything other than a tree, and the grass looks so choppy, or bumpy, that it could be mistaken for choppy seas! Then I think about the imaginary tornado, and that suggests the possibility that the tree could actually be a waterspout! Then I think about how fog might never be dense enough to block a view of trees, except one, because if it blocked the view of all trees in a context, there would barely be a tree seen in the photo! This leads me to think of the possibility that this could be a really talented form of art (maybe digital art), since it's so vague-looking.
NOTE: My observations of that photo came through after looking at the photo a couple of times, not just looking at it the first time.
