Dreams often contain symbols or metaphors that are specific to the dreamer. Having anything hit one's back suggests influences from the past, or perhaps an attack from an unexpected direction. "Fish" have numerous symbolic meanings, from food to religion to the expression "something's fishy." The dreamer needs to determine what meaning "fish" has to the dreamer in order to understand what the attack from behind might mean.
That depends on the severity and how often you dream them. In this case the dead fishes would be known as Latent Dream Content or the things we don't understand about a dream that often have some deeper meaning. The mob used dead fish to convey the sense that someone was about to be killed and thrown into the ocean hence the saying "Sleeping with the fishes". Your dreams probably mean nothing serious...unless of course you disrespected the mob in some way.
it means you are having to do all the dirty work in life
If by "hitting" you mean literally hitting, then no. You cannot get pregnant from someone hitting you. If "hitting" is meant as a slang term for sexual intercourse...then via anal penetration, no. Via vaginal penetration, yes, you can get pregnant.
it means you had a bad dream, now go back to sleep and dream nice things!
It means you want him back, but you have this feeling that you can't have him back. Do you get what i'm saying?
The walls in your dream are a literal picture of the figurative expression, "we've run into a wall." That means that your efforts to make progress have run up against an obstruction or difficulty. The dream reflects your feeling of frustration.
You may still have feelings for him.
The question could refer to hitting a baseball or a punching bag or a target or an opponent. In general, the dream is probably expressing feelings of frustration and incompetence. The dreamer is making an effort to no effect.
Dreams communicate by using metaphors. Hitting someone with a crowbar represents an urge to violence. This is a good dream because it relieves the tension of the dreamers unexpressed feelings.
It can't be said that your ex boyfriend may never get back with you, but, when you dream of getting back together again it's simply a dream because you are always thinking of getting back together again and the dream doesn't mean you will; time will tell.
it means you had a bad dream, now go back to sleep and dream nice things!
you not over him go get him back if you still love him
