Moments of revelation

Do you know those moments of weird revelation when you, all of sudden, begin to think deeper about this life, causing you such a terrifying feeling that could even give you goosebumps?

Well, I have no idea if you've had this kind of moments, but I can say that this has been happening to me since I were little. I still remember that day when I got off the elevator, at my grandma's, and then I had this curious, strange feeling that made my mind go in the deepest aspects of this life. Dunno, but in these moments, I swear to God I feel like the tiniest, most unsignificant thing on this planet, and think "What the hell am I doing here?".
On one hand, this may be benefic to me, because it makes me realize the majesty of life, but on the other hand, it scares the sh*t out of me. You know, just thinking about all this weird stuff, which is actually the truth of our existence, makes me so puzzled.

But is this the real truth?
Do we really know the truth of our existence?
We know nothing for sure.
