What is real?

I'm sometimes very disconcerted by reality. I mean, what is this, really? Everything is held aloft by nothing. It's not so obvious that anything makes sense. Yes, science confirms some consistency, but that's all. It's like simultaneously everything and nothing matters. What are you supposed to do with that? It's almost like we are meaning machines, as if that's the only difference between us and animals - the ability to ascribe meaning. Is this just some pretentious rambling? Probably. I doubt I would be very concerned with meaning if I were any less sure of where my next meal or drink was coming from. So what the fuss?
