Perhaps doing a ritual work where you create a barrier against unwanted intrusion, a clearing of the space around you, and an invocation of Light and harmonious energies (ie, a SOP, for example), would be helpful. It seems to me, just off the cuff, that one or both of your parents, either intentionally or nconsciously, is beaming stuff at you, and this is bouncing in and effecting your divinations. See if doing a clearing and protecting thing of some sort would help.
