I only remember part of the end of one dream from last night probably because of interruptions because of diarrhea/gas/et cetera, my memory is unclear so I am not sure if the earlier parts of the dream were on a train or not, but I think that I was traveling with people I know/knew on a vacation trip maybe on an underground subway or building or inside a windowless building.
There were probably other people there as well but I can not remember, everyone was having a good time, and then I think that a group of dangerous mafia-like men led by a little girl or a little woman or a little female being with whitish colored skin with blackish colored hair who reminded me of my dead female cousin AE (for some reason(s) that I can not remember) started attacking/torturing/murdering everyone.
