DiSTuRBiNG DReaM

i like nightmares but sometimes i have dream that isnt scary but still freaks me out. i had a disturbing dream a few days ago
i was in a car with my dad (dead) and my brother (i think) and the car ended up driving into the yarra, as it sank i thought/said to wait till it hit the bottom and we could swim out. the water was crystal clear. it hit the bottom but then we started driving around under water. next thing i was walking around under water. i had trouble breathing, i then thought i must be dreaming walking around cos i was dying. i asked someone who looked like my sister if i was dreaming walking around because i was actually drowning.
she told me i wasnt going to die, (heres the scarey part) i was going to die 2 weeks after my 2nd child was born. then i woke up.
even though im hetor im a not a breeder, so im not sure what scared me the most, the death prediction or the idea that i was going to have 2 kids
