buried grief?

Date: 2/4/2019

I woke up this morning crying my eyes out and my just a little cry, I mean like EXTREMELY crying for 20 minutes.. The dream started with me working at a store and I got into with a fucking YouTuber, of all things, that came through my line and was just being a total dick. I checked him out and then a few minutes later I went out for my break. The YouTuber and his friends were outside looking for their heroin they dropped and I ended up finding it and tried to take a little bit but decided not to because I've been clean for a month and a half now so I just gave it to them and they left.. Finished my shift at the store and then went to my job at a movie theater where I was counting down my drawer and had 40 on the counter but it went missing and saw a guy and his wife take it.. I told the manager about it and she told me to step outside while she went and confronted them about it.. Well I went out for a cigarette and out came the couple talking shit to me for saying anything about them taking the money and I just laughed and takes shit back until the lady came up behind me and started choking me which I still found funny but then they got in their car and pulled a gun on me but luckily someone walked up and they put the gun down and told me to watch my back.. I freaked out as started crying told my boss and she left me leave early. I went to try and seek comfort from my family but they didn't give a shit about it at all. So I went to my step-dad but he was pissed I showed up without calling and then left without stopping to talk to me he just threw some note out of the window. Then next thing I know a group of people came up to me with sympathy in their eyes trying to help me out and comfort me lol and then I wake up bawling my eyes out.. What the fuck does this shit even mean? It was the most random dream ever and are absolutely no sense to wake up crying as hard as I did for only god knows why. I looked up what it means when you wake up crying in dreams and in the notes section of this, I put the answer that I found.. Says something about touching up on some buried grief.. But I still don't see what grief I touched up on in this dream, it's confusing as fuck.
