Aickman's movie parallel

Please tell me that someone has seen the movie Identity? SPOILER FOLLOWS (in case you plan to see the movie) Does this not strike you as something along those lines? You have several characters interrelated by a common thread, but you don't find out what that is until the end. Could these four all be the the same person like the serial killer in Identity?? You see, they are all interconnected by a collective conscience/memory... Naturally, the four are brought together to common location to discover why they have convened throughout the series of events that reveal a greater connection. I don't know, maybe I'm just making something out of nothing here. What do y'all think?
