Short Attention Span

Does anyone else here feel like you're detached from reality? It feels like I can't even remember what I've read whenever I'm reading books or an Internet post, for example, I have to save a web page and look back at it even if I find it interesting enough, I wont remember what I've read, nor can I remember conversations. Does anyone else have this problem? I tend to space out a lot so that could be a reason for my awful memory
