last night i had an almost identical dream to one i had approx 6 months ago...where my family were located, it was being bombarded with an aerial assault, fighter planes dropping bombs. Me and my family were on a train, planes flying ahead, we decided it'd be safer to walk by the railway lines rather than carry on in the trains themselves, bombs were hitting the tracks but for some reason only causing slight dents in the tracks...
spooky....
perhaps the OPs dream is related to an insecurity she has, i.e. do you trust your boyfriend, trust him when he's with other women etc...
maybe your dreams relate to trust issues...and your brain is speculating in sleep..
as for dreams, i have freuds 'the interpretation of dreams', yet to be read and about 20th in the pecking list of books to be read....currently reading 4 on the go...
