This dream may symbolize unresolved feelings or issues related to your past relationship with the old hookup. Being in his childhood room represents a return to a familiar and comfortable place in your mind. However, the presence of his alcoholic mother and stepfather may suggest that there were negative influences or conflicts in the relationship. The fact that they forbid you from sleeping in the same bed as their son could indicate feelings of guilt or shame about the relationship. The Jack and Jill bedroom, which connects to the old hookup’s room, may symbolize a connection or lingering attachment to the past. The smell of cigarettes in the master bedroom could represent unhealthy habits or behaviors that were present in the relationship. The twin bed next to the parents’ bed may symbolize a lack of intimacy or closeness in the relationship. Texting the old hookup to come get you could suggest a desire to be rescued or saved from the uncomfortable situation. Overall, this dream may be a reflection of your subconscious processing and trying to make sense of your past relationship and its impact on your life.
