Late Night Snacks and Nerves

I have a peculiar habit of eating snacks at midnight. I know it's not healthy, but something about the quiet house makes me feel less alone. Last night, I caught myself laughing out loud while snacking on chips in front of the TV, and then realized why: my high school crush was on one of those nostalgic 'Where Are They Now?' videos. Seeing him again after all these years sent a shiver down my spine, even though I haven't thought about him for decades. Am I just being silly, or is it normal to have such reactions at this age? Is anyone else out there still surprised by random emotional triggers like that?
