Is it common to feel this way when you're over 30?

Does this happen to everyone? perceiving everything as exactly how it is. your outlook on everything changes and it doesn't go away like it always did in the past. you are stuck with it *reality* and it's not going anywhere which kinda forms a deep jadedness. i hope to get use to it, i try to adapt and enjoy the moments. everything interests me, but nothing holds me. I attend to everything, dreaming all the while..but still sometimes it pierce through and confronts me
