Hey Joker - I'm pretty sure I've experienced that Vortex too! It's not something you actually see so much as feel and sense....
It's usually after an evening of beans, beer, and a desert - there's this sort of stirring inside - then BAM! BAM! and pretty soon there is this vortex you sought of walk into and if you don't get out soon, your eyes go watery, your nose develops a nervous twitch, and it can get pretty hard to breathe.
It can be a deeply spiritual experience for those forced to remain in the cloud left behind. I think the best place to share this experience with others is in a crowded lift....
