That's kind of strange... I was a weird kiddo as well (kind of a different topic), but my mom told me I knew and understood what death was at the age of around 4. One time while we were playing hide and seek I apparently just sat on the bed and quietly waited for her to come out. When she asked why I wasn't looking for her I just said I thought she was dead (yeah obviously that creeps me out). After talking to her about it she was floored because I didn't mean it in a "I heard of the word dead and decided to use it" kind of way, but in a "I understand what it means for whatever this reality is not to be present anymore and the universality of death. We're all going die one day and that's ok... Don't you get it?" calm kind of way. She was astounded and tells me about it from time to time. I also saw my cousin after many years one time and wrote him a small uplifting note and told him he would need it soon and to read it again then. I don't know how, but I just knew someone close to him was going to be in bad shape pretty soon, there was sadness coming his way. His dad (my uncle) was diagnosed with cancer the next week. One last weird thing - and this has happened twice now - is that when I talk to people about this kind of stuff in depth their minds suddenly go kind of... Blank. And they forget completely what we were just talking about. The first time it happened with my mom - she looked like a deer in head lights with her mouth hanging a little open mid conversation and froze for like that for a second. Then she just started talking about something else like it was nothing. Then I immediately forgot what we were talking about too but still was like "wait a minute.. weren't we just talking about something else?" The second time it happened with a very close friend. We were having that same conversation and I remember it got really deep and I wanted to push further, but then when we did she just popped and blanked out the same way my mom did but this time my friend said "Wait... I don't remember anything we were just talking about." Both times I forgot what we were talking about shortly after too, but I knew what it was about, like having a word at the tip of my tongue and only being able to describe it. That's why when it happened the second time, it was like finding my footing again, I was like HEY this was the conversation I was having with my mom that one time a long time ago and I got really excited, but ultimately forgot it again. All I know is that we were delving somehow deeply into the topic of death, and that's all I can recall. One night I also spontaneously had whatever thought it was that we were talking about those two occurrences and rushed to write it down, but of course as soon as I tried it was gone again.
