This question is not clear as to whether the dream is about the kid's dad or stepdad. But it might help to understand that your dreams are about your own emotions, including your fears and self-doubts. Dreams do not provide any supernatural insight into parentage or family history.
No his kids are not mean they all got there attitudes from there dad
This dream illustrates the dreamer's feeling violated by somebody who should be protecting her/him.
don't worry my dad doesn't abuse me.
you miss your Dad
The dream means that at some level of your consciousness you realize that your dad is growing old. Your own mind might be showing you that your dad has more health problems that he is willing to admit to you, or that you are willing to recognize.
Let's just say that's not a good thing
Dad's Weird Dream was created on 2006-09-11.
This dream suggests that the dreamer has not finished grieving over the loss of the father. It is not unusual for grief to persist for many years.
it means he wants to have kids
This question brings to mind the common expression among kids, "My parents will kill me if they find out ... " The dream strongly suggests that the dreamer has mixed emotions, including guilty feelings, about some personal behavior and its consequences.
Without further information, it is difficult to suggest any interpretation. It would make a difference what your dad and the ghost are doing; for example, a dream of your dad fighting a ghost would have a different meaning from a dream where he is just standing around with a ghost hanging nearby... or dancing... or singing... or whatever. The emotions you experience during the dream are also important and make the difference between a nonsensical dream and a terrifying nightmare.
Your dream is a literal illustration of the idea of giving your love to your dad, suggesting the hope that your love/heart could restore him to life. The actual meaning of the dream depends on whether or not your dad is living now. It could mean that he is dead in the sense of being unable to express his feelings, and by giving him your own heart, you hope to stir some emotional response in him.
