<human>: Can you give me the gist of the text in a nutshell?

Last night I was laying in bed, reading A Feast for Crows. I wasn't tired and was very engaged in the book. After reading a particularly thought provoking paragraph, I laid the book down for a second and thought deeply about what I'd just read...but then something happened. In a fraction of a second I completely forgot everything I'd just read and could not even remember what I was thinking about the second before. I tried to remember, but nothing came back to me. I could recall what I'd read before the paragraph I'd just finished, but that's it. It was like I hit F5 on my brain and then restarted it. So, thinking I've just had a stroke or something equally pants-filling, I mentally go through my name and address and phone number, family members, classes I took this semester, etc. Everything is in order. It's just the last paragraph and literally *everything* in my brain at the time that I read it that's missing. Any ideas on what the hell went down??
<bot>: I experienced complete loss of memory of something I'd just read (including loss of thoughts that went through my brain while reading). What happened?
