Your dream is very complicated but i thing this is the thing you think more or you afraid more that,s why you have seen such a dream.
Mostly we see the dream we like the most or we afraid more.
so don,t think about it more it only a dream of your my friend.
Same happens to me in my dream last night but i was having sex with an unknow girl and i was shocked that she want from me more and more even tough i can,t bear any more but she want to have more pleasure from me. and she was blackmailing me if i don,t do this she will call the police.
