I saw a group of people cleaning out an apartment of someone recently deceased, a friend. Who in reality died years ago. I entered and looked through his belongings after they left. I found 2 wallets, one with cash and drugs. Than I discussed that person's mother having died recently also. And at some point I also visited an empty pool near the apartment
In general, dreaming about deceased friends represents unfinished business or unresolved issues. The dream could be a way of processing and resolving these feelings. The act of cleaning out the apartment could symbolize the desire to let go of the past and move on from these unresolved issues.
Finding the wallets, one with cash and drugs, could represent conflicting emotions about the person who has passed away. On one hand, you may have positive memories of your friend, represented by the cash in the wallet. On the other hand, the drugs could represent negative aspects of your friend's character or lifestyle.
The discussion of the mother's recent death could represent a feeling of loss or grief that is ongoing. Visiting an empty pool could symbolize feelings of emptiness or emptiness of emotions that a death can bring.
Overall, this dream could be about coming to terms with the past and letting go of unresolved emotions related to the deceased friend and their mother's recent death.
