Have any of you had these? I've read that generally they are mostly indistinct noises.

My estranged mother who is currently living with us for a couple more months (me and my grandparents) is someone i do not get along with. I want all the best for her, i just don't want her in my life. 

She suffers from extreme depression and bipolar, and there have been many nights where I've heard her crying/sobbing.

Obviously,  that triggers my anxiety like a mofo...

As a result, i often think i hear her crying (I'm downstairs she stays upstairs). It's always just quiet enough that i can't be sure, but just loud enough that it pecks my subconscious mind and i feel my anxiety growing without knowing why. Then as the anxiety is building, i suddenly consciously notice the sound and I get a massive twinge of guilt and extreme anxiety. 

If i sit super still and quiet, i try to listen to see if that is indeed her crying.  Almost every time, it isn't.  In fact  every time it isn't,  but since I've heard her cry before, my mind goes to that. My grandpa watches tv right above my room, and that's what the noise is. I've gone upstairs mutliple times to make sure. 

But. just the volume it's at and the way it permeates the walls, the pitch of it resembles her crying and gives me MASSIVE anxiety.  Mixed with anger and sadness of course. 

Does anyone else have an experience like this? When i was younger living with my parents, I'd often get massive anxiety just hearing their voices when they'd drink and i waa trying to fall asleep so I'm sure that PTSD plays into this quite a bit. I also can't do apartments because the loud footsteps and muffled voices through the walls has me constantly alert and in fight vs flight mode.

 Working on getting over it but it's not easy and i feel like i have to dissociate so hard to get past it.
