hi,
just a few thoughts,
corridors are places of transit,they take you to diferent areas of experience,it seems important that you are being sick in this area,have you been through ,or are you going through a dramatic change of some sort?work,marriage,social upheaveal,sorry about the pun,but thats what vomit is ,an upheaval of sorts,
the corridor is also the place naughty people have to stand,is there something that is making you feel sick?better out than in as the saying goes,
these are only questions that may kickstart the thinking process,or not,
recurring dreams usually mean that ,the subject in question has not been dealt with.
these are just my thoughts,and may be of use or not,
