Real?

Do you ever get that feeling that when you're looking at something, it doesn't feel real? You sit there for hours and stare, and yet, your mind still can't make up it's own opinion.

Now, I'm talking about the full on 'Matrix idea' on how we're living in a controlled world, and what we are seeing isn't real! God no. I'm just saying how I sometimes get this feeling, that what I'm looking at isn't 'real'. It's hard to explain really, and it's incredibly frustrating.
I think it may have to do with me worrying and to me over-analysing EVERYTHING I do.

But yeah, do any of you ever feel like that? Feel like something isn't 'real' and you're unsure about it, but too scared to question it?
