What are gambling dreams about?

It was a simple dream. My relatives were in it - all deceased. My mother handed me a letter from my aunt ( we were estranged when she passed). In it were two $200 bills. I said to myself there is no such thing as a $200 bill. Then I notice all these raffle tickets. Now, in the waking state I never gamble on lottery or raffles or anything really. I never win at games of chance. So in the dream I want to toss the tickets. My uncle says no, keep them. One is oddly shaped like a narrow long pointer. He hands it to me. My uncle was good with money in real life. What do you think it means?

I was in a cave and found a plastic bag which transformed itself into a flying fox, which led me to a long cabin in the woods with several gambling machines inside it. The fox’s eyes glowed green and it let me see into the eyes of one of the people who lived there. It was a guy in a car with an obnoxious mafia accent who was bragging about how many dudes he “whacked.” When they reached their destination, he tried to knock out the dude at the door but failed. He tried 3 more times but still failed. Then the vision ended and I saw all the guys gradually gathering in a circle and debating why they lost their mark that night. Except one dude, a guy in a hawaiian shirt, was letting out a long continuous scream at the top of his lungs. Everyone told him to stop but he ignored them. Then when the circle became half full, the guy was still screaming and everyone congratulated him on his lung capacity.

Then I woke up, went to the bathroom, and fell back asleep. This time I was on a train with all the Harry Potter characters. I told them they should all be social distancing and they decided to pile on top of each other on my side of the train. I jumped out the window and Bellatrix started chasing me. She transformed herself into Chewbacca and caught up to me. At that point I used Avada Kedavra, missed, and then an ancient scroll she was holding began glowing, levitating, and unraveled itself. Then I woke up again.

I dreamt of 4 massive mines. People were investing money on the mines as a sort of competitive gamble. Whichever mine contained the gold or whatever would make the bidders rich. Everybody thought they were going to get rich. However, the mines were secretly owned by the same people and had been stripped clean years ago. They were using the "game" to gain power over the bidders.

The dream then switched to a man in a south American country. (Although, the countries on the map were all different names. I do remember one country on the map (a neighboring counter around where Venezuela would be) had Frankenstein in the name. The population in the country felt more like Scandinavia, though the way it looked felt kind of irelandish).

There was a man there who found he could pick up items using relatable sound waves. It was like he'd found a magnetic within non magneticproperty materials. And I think he wanted to use it to find the fold in the earth for some greater purpose than money though. But the government was keeping an eye on him.

I went to this guys place to rent out space, without knowing all that. I went to the restroom and noticed there was this weird water balancing divice for a time keeping kinetic energy machine. I cant remember what it was used for. But I then realized he understood kinetic flow and self perpetuating motion, and I wanted to learn from him.

It turned out that he was being prevented from leaving the country or patenting the technology, because the government didn't want anybody to know about it. And, now that I had an idea, they may try to keep me from leaving too.

I left the place to try and investigate his situation, and there was this man on the street. He sadly said something (I cant remember what he said, but it was a statement of a problem like being lost or something). I could tell he was a government official trying to lure me in with his helplessness, though. He was just baiting me to figure out what I knew.

I dismissively said something like, "sorry buddy, I cant help you." Then a bunch of others on the street swarmed in. They started very aggressively (but with a helpful demeanor and smiling faces), demanded he find his way. They were all pushing him towards "help" while he continued sadly saying how sad he was.

I turned to get in my car and leave, but this old woman (with a smiling face and helpful
demeanor) got in my face too. She kept repeating something and walking into me to push me wherever she wanted me to go. I kept telling her to stop and leave me alone. She wouldnt. So I ended up slapping her really hard. She didnt even react. She just continued exactly what she was doing. I repeatedly slapped her back and forth, but her face didn't even budge. Then I woke up.

Salary I don't remember that much from that dream. I remember that I was playing a gambling game with 2 of my classmates (I don't really know them that well). The game proceed like that: There were 2 drinks per person. They looked identical with one thing that separates them: one had a deadly poison in it. They went to their home and everyone in their home was supposed to to drink it. I felt well after drinking the drink. Well, for a short time. I began feeling very sleepy. That was an indicator that I have drank the drink with drug. I called the organizator of the game to ask him for mercy, give me the antidote. He said that he will come to my home. I began feeling very sleepy. My eyes were starting to see black squares. I fell on the floor. I immediately woke up. That means I had died in the dream. It wasn't much of a nightmare more of a surrealistic dream.

My mother (dead), grandmother (dead), sister (2nd eldest, the wise one) and Brother in-law all moved to a new place. They all sat down in a park area to play blackjack (income from a family of gambling addicts) and I decided to wander off to view the sunrise. It was incredible. Coming up over a lake I was stood at the bank of and just turning the sky red over the suburbs beyond which made me think it was ominous.
My grandma came over to watch it with me and as we were sat a giant bat flew over us and to the water, as it flew away we saw an alligator in the water and it was coming towards us. I quickly tried to move grandma and we shuffled away to safety. When I looked back, it had instead attacked and eaten a bay (brown) horse which had appeared where we were standing (I’m a horsey person if relevant)
We then decided instead to sit down with the rest of the family and play blackjack. I won about 3 out of 5 hands.

That’s it..And then my brain travelled to some other random dream..

Any ideas?

Before she passed my mum gave me a dream interpretation book.. what I have so far:
Alligator = cunning
Brown horse = earth and connection to it
Sunrise = new beginnings

Is it a warning for future ventures? I really have no big plans at the moment apart from paying bills!!
