I am not a believer in highly metaphorical or symbolic dream interpretation. I find it complete pseudoscience.
I believe, based on my experiences, experiences I've seen with others, that dreams are basically a combination of rehearsal and randomness.
Randomness because of your lower state of consciousness, rehearsal because that's how we survive, by being prepared.
We tend to have nightmares about the things we have underlying fears of happening in real life. They don't have to be 100% accurate.
For an example, many police officers and war veterans have nightmares of having to defend themselves against an armed attacker, only to have their firearm not work properly, maybe because of something that could happen in real life like a mechanical malfunction, or something less realistic like shooting their attacker over and over but with no success, or shooting but the bullets just falling to the ground in front of the gun.
A victim of sexual assault might dream of being sexually assaulted, but with their assaulter having supernatural powers or the circumstances not making any sense.
Dreams have a large element of randomness to it likely because of the same things that make our minds wander when we're awake, at a reduced state of consciousness our mind wanders and we think things that when we're more 'with-it' we know make no real sense.
Positive dreams may be nothing but randomness.
Negative dreams you'll usually find have strong parallels with something you fear actually happening in real life, it's your brains way of preparing for how you'll react should it happen. Hence why trauma victims are at much higher risk of having nightmares related to the trauma or other anxiety provoking situations in their life. I had something happen to me when I was pretty young, like 9 or 10, and I had nightmares of it happening again, not usually in the exact same way it actually did happen, but some similar scenario of being attacked in the same way with the same weapon but in a difference situation by a different person. I don't have those nightmares very often anymore, but I did for a good 9 or 10 years after I was attacked.
In this case the correlation is probably that you have or had anxiety about how your father would react, and fears of being caught, taking away your ability to control how he finds out.
Just my 2 cents.
