Feeling somewhat nostalgic but nostalgic for what?

I wonder if nostalgia triggers a specific kind of hormone in your brain because it's being triggered right now. And I don't know what I'm nostalgic for. I just know that I'm somewhat nostalgic.

Not sure if that made any sense but I often don't make any sense.

But this is good! Because I feel like it is late at night and that I shouldn't be staying up. This is good because at least I don't feel like I *should* be up because of jet lag.

...

I have a feeling that only I get myself. Like whenever I finish typing something I think back and wonder what kind of nonsensical crap I've just spat out.

(Interesting tidbit: I just typed sput instead of spat and didn't realize it was wrong until Firefox told me.)

But like you know how only you "get" things and when you try to put your thoughts down you know what you're talking about and as long as someone else has experienced it before all the words are there to have them know what you're talking about but for a person who has no clue, they just have no clue.

God I'm having another one of those nonsensical crap moments. Probably because I'm too lazy to reread what I'm typing and edit. Actually at this point I'm kind of afraid to reread what I wrote in case it will make me die of shame knowing that I was its creator.

There I just reread and edited the last paragraph so that it's understandable to other humans. Hopefully. Anything else I'm neglecting to reread. Off to write something.
