How can I communicate with my deceased mother?

My mom passed December 11th 2025 and I’m still mourning her badly. I cry almost everyday about it, because the system failed her basically and she was on drugs really bad and everyone just gave up on trying to help. She died of an overdose and i still cant get over it. I’ve been talking, praying to her (or myself?) in hopes she hears it. I don’t really believe in god, but i do believe theres some sort of spiritual being(s)out there. I’ve looked up ways to get her to communicate — few things i’ve noticed happened since she died is stuff dropping, curtains moving. I hear footsteps, literally things making noise. i do live in a foster home with another person and i do have cats.. but everyone is always asleep when i’m up late. The cats all sleep in my foster guardians bedroom or in the basement.

So is it just coincidence or do you think she’s been here all along? Earlier, i was finishing up with work and i settled down, turned my red led light on. I was just minding my business on twitter when i heard something fall all of the sudden. I turned my flashlight on to see and it was my bag thats been sitting steady in the ground since yesterday. Out of nowhere.. i haven’t moved it at all, just took things out of it hours ago but nobody touched it to make it lean over and fall like that. Can someone please tell me what this means or if i’m all in my head? I wrote a note for her in a notebook and placed it on top of the bag that fell. Or could it be other entities? Just let me know what you think..?
