Geico commercials make me uneasy?

I'm sure everyone is aware of the old GEICO commercials, like the farm one, the money watching you and the caveman one that somehow warranted a TV show (which thankfully failed). I am not American, so these commercials are not part of my childhood, and I discovered them through watching those nostalgia compilation videos on YouTube. However, for some reason, they make me feel uneasy. If it's the middle of the night, and the song from the caveman commercial pops up in my head for some reason, I cannot sleep. The GEICO gecko itself even scares me, like if I see it at night, I find it hard to focus on the screen. No one seems to experience the same thing as me, as I already tried Googling to find any Reddit posts and there were none, so it seems it's just nostalgic for most. There's no possible reason I could have for being terrified of it, it just unsettles me. Is this normal?
