Hmm what does it mean when u dream of winning the lottery?

I dreamt my mom bought about 30 scratch offs. She passed them to my sibs and I to scratch off. My sister scratched one off and it was a winning ticket of 151,000! We were all excited and then my sis says its her money and she's not sharing. I became upset becuz it wasn't her ticket, it was my moms.in my dream my mom said she could have it or to share the winnings. My sis and I both walked 2 the gas station to claim "her" winnings and she only received $57 the rest would b mailed to her. Then I woke up. What do you guys think it means?
