Do you ever creep yourself out?

Depends on the level of Creepiness. If it's about light things, then no. But if you talk about the deeper inner-self, then the answer maybe a resounding YES.

Then again, human's mind maybe is the most indecipherable thing under the sky. The truth about having minds like ours is; we can't be sure about everyone and ourselves.
You think you know someone but then go all perplexed when you realize you don't know them at all. Same thing with ourselves, we think we know ourselves well, but then we found out that..........(isn't this why we dubbed our lifetime as somekind of 'journey' to find ourselves? I'd say it's a journey to know ourselves though).

Yes, especially when I hear stories of what I apparently did when I was drunk and have no recollection of it!

When I consider that the universe either has an end or doesn't, I creep myself out. Because if you think about each possibility for a second, it quickly becomes impossible to grasp either one.

Often!

Yes, when I see a spider.

Yep, in many ways.

i creep everyone out

it happens.

As a student, I creep out by what the industry I'm bound to work for is doing to the human species. One result: our children will have a life expectancy >5 years shorter then ours and it's all caused by our greed.
