They are: uncle drug addict/captive poisonous snake/wild boar at home.
There seems to be no connection, but I think they are all responding to the same theme-you are setting yourself on fire, but you want to avoid risks as much as possible.
Uncle, taking drugs is dangerous, but your subconscious mind is borne by someone who has little contact with your family. This is an escape.
In the part of poisonous snakes, poisonous snakes are inherently dangerous, and this danger is not only caused by you. What is important is that there are still people in your family who don't know, and you don't want them to know and get hurt. You hit it, let it bite wood, and put it in a plastic bag. These are your ways to avoid risks.
Wild boar is similar to poisonous snake in part.
To sum up, I think this dream may reflect one thing in your real life that you have to bear because of you. Of course, this thing is not a good thing either. You're not going to tell your family, and you don't want it to affect your family.
On the one hand, you feel responsible for this "bad thing", on the other hand, you also want to settle this matter and not let your family know. . .
This dream is about this anxiety.
