No, it's not just you. Let me tell you a little story I found pretty amazing.
One day I was sitting at my friends house playing Mario Kart on the super nintendo. We used to love to play that game drunk. Anyway, I vividly remember this. I remember it so well, I actually remember what game we were playing and everything. Mind you, this was about 8 years ago.
Anyway, something out of no where just hit me. It was like this epiphanny to some problem that I didn't even know was a problem. It was the strangest feeling I have ever had in my life. I tried to explain it to my friend the best I could, and I even gave it a name and called it "knowing." From that spawned, there are two types of people in this world. People who "know" and people who "don't know." Once you know, you can easily spot the people who don't. I know it sounds really bizzare. To make it even more weird, You know you know something, but you just can't explain what it is.
So years and years go by, and I don't think about it that much anymore. I even start to think: "Man, was I just a high idiot thinking about this? Did I just make all this up?" And then it happened...
I met this guy in college who is now a great friend of mine. Probably my only true friend. Anyway, he used to work 3rd shift at a BP (gas station) I was in there on my cell phone, talking to my other friend about knowing for some random reason. My friend who worked in the BP only heard my part of the conversation, and heard me say: "Nah dude, he won't know what I'm talking about." I hung up the cell phone, and of course he was curious on what HE wouldn't know. So I start to explain, but I start with: "OK, you're probably going to think I'm an idiot and this is totally stupid, but... there is this thing that some people..." and he finished my sentence and said: "You're talking about knowing? How some people know, and others don't? And you can't explain what you know but you know you know?" My fucking jaw dropped. I couldn't believe it. He even came up with the same label for it I had. I remember almost crying at that point, because there is NO WAY that could have been a coincedence. This convinced me that there is something weird that happens to some people.
Anyway, enough of my rambles ...
