With my savings in hand,my dead grandmom and me went on a day out and watched a movie in the theatre whereas in real life I've never watched movies in theatre with her. We watch and certain people tryna take our seats and I tell them no and go to washroom and come back without my pants and notice my pant in my seats and gradually taken them and put it on when its all dark in theatres. A police watches me and tries to scold me but I speak boldly to him. Me and my grandmom get out of the theatre and I ask her if we can go to beach now and she was like sure, if you'd like that but then I tell her that its almost night, lets get home.
This dream may represent your desire to spend time with your deceased grandmom and the regret that you were not able to do some activities or experiences with her before she passed away. The fact that you went to the theatre with her in the dream may symbolize the desire to spend quality time with her doing something different or new.
The conflict with the people trying to take your seats could mean that you are trying to protect your memories and relationship with your grandmom from interference or external negativity. Losing your pants and taking them back while being watched by a police officer could be interpreted as a fear of being exposed or judged by others in your personal life.
The suggestion to go to the beach may be a representation of the need to seek peace or tranquility in your life, and to create new experiences with your grandmom, even though it's too late to do this in reality. The decision to return home implies that you are aware of your responsibilities and obligations, but you should still cherish the memories and moments that you have with your loved ones.
