2 BAD dreams about my mom?!?

This is the 2nd bad dream I have of my mom...the 1st one happened towards the end of february...i dreamed that I was in a store with my dads side grandma & aunt...they were looking for clothes to buy for my moms funeral...while there I found a purple seashell that I wanted to buy so that I can put in her coffin...amethist is her birth stone...i woke up right after...i dont know how she died in my dream...also, I felt like I was younger...THEN, about a week later, I got in2 a HUGE fight with her & she ended up kicking me out the house...it was a very nasty fight...words were said on both ends that I know we didnt mean...we had NEVER had a fight like this...basically, she found a small bookbag in my closet that I was holding for my boyfriend with a little pot in it...i dont smoke, I was just holding it for him...so, I dreamed again about an hour ago, I did some research here first, but couldnt find much...thats why I decided to write...in this dream, it was me, my mom & some rasta looking black guy, very dark with dreads & a jamaican inspired headband...i was standing in the living room, the rasta guy was sitting on the couch, & my mom was in the kitchen...the dream was based on a 'drug deal' my mom & rasta were the 1s talking business, but he kept telling her she was short in $$ or something...i know that the deal was going bad but he was acting really cool & nonchalant about it, like he didnt care cause he knew he wasnt gonna loose...my mom isnt good under pressure in real life...after a few minutes of talking I heard my mom say she couldnt take it nemore & said she was gonna kill her self...i ran towards the kitchen & saw her with TWO guns pointed at her...1 in the heart & the other in the stomach...i cried & yelled at her to plz stop but she didnt listen...there was a blank look on her face...she pulled the triggers & I caught her & I started screaming 4 help while dialing 911..what could all this,mean? Plz,help.. SORRYSOLONG..TY
