These appear to be tickets to a vacation destination that exists in several realities at once. The information on the tickets seems to change before your eyes: "…all-expenses-paid trip to…" "…series of nested pocket dimensions…" "…where pain has no meaning…" "…complimentary continental breakfast…" "…transmutes flesh into a fine mist…" "…cruise in elegance and style…" "…unbound by the limits of linear time…" "…largest wooden rollercoaster in the Andromeda Galaxy…" On second thought, you feel as though you don't need a vacation that badly. (This item can be safely discarded.)
