I dreamt that there was some sort of reunion party going on, at which several of the kids I grew up with were present, as well as a whole mess of movie stars (I distinctly recall Jeff Goldblum arriving by bicycle). One person in particular who was there was a girl I had a major crush on all through elementary and junior high school, until her family moved away. She looked just like she had back then, except that she was much taller as an adult now.
She was wearing this pale blue dress with one side/strap deliberately slipped off to expose one breast. It made me feel really awkward, because I wasn't sure if she just didn't realize she was flashing everyone (most especially me, since it was me she was talking to the most) or if it really was deliberate for some reason. I was trying to work out some way of "suddenly, politely noticing" that wouldn't embarrass her in front of anyone else and which wouldn't make me seem like I'd been oggling her this whole time... tough social problem. I was working on it when all of a sudden I started choking.
Apparently, people had started to run a lot of software inside their own bodies, and web browsers had replaced or in some way become critical to basic body functions, and the version of Netscape I was running had just hit some kind of major systemic incompatibility, and I was choking and suffocating while my immune system searched the world net for an older version that was still compatible. When it found one, it autoloaded it and the horrible suffocation ended, but by that point I couldn't care less what was going on with anyone around me.
