do you have a landlord/neighbourhood watch or a strata council? contact them and make them understand that this is a serious matter, and they should contact your neighbor's to investigate! 

Be careful when answering your door, if  you don't feel safe just talk through the door. consider installing a peephole and a chain door lock, if  you don't already have them. (don't cheap out on the lock) (if you rent you may be able to get reimbursed)

Do You Know Your neighbors well Bri? anyone been talking about similar situations?

if you do. I would suggest knocking on their doors/calling them, if not leaving a letter describing what you experienced and if anyone else is having strange occurrences? 

Be safe, not sorry. spend some time putting in some work  to protect yoursand your neighbours well  being. 

Take care, 

Hi @Petey_BOI

I don't know my neighbors well.  I'm a private person.  I may contact my landlord.  I don't open my door. With the pandemic, if someone is at the door, I speak to them through the door and look in the peep hole to see who's there.  When this occurred, I looked through the peep hole after they knocked and did not see anyone there, so I thought it was a package delivery and opened the door later to find a rock.
