So there is also a view that dreams are your subconscious talking to you. ?
When you dream that a bug comes out of your finger, there are usually two possibilities:
1.? Physical health signal
Fingertips are numb or tingling. But the pain is not enough to wake you up from sleep, so it will be manifested through dreams.
Maybe a bug got out of your finger, or you dreamed that your finger touched broken glass and had a wound.
In this case, it's like you are in a hurry to urinate but haven't woken up from your dream. It's easy to dream that you are in a hurry to find the toilet, but you can't find it anywhere. Either the toilet is closed, or there is the opposite sex in the toilet, which makes you want to go to bed but can't.
This is the wisdom in dreams. Although both the subconscious and the conscious sense your urgent signal, you are not awake at the conscious level. The subconscious mind creates a dream for you first to reduce the urgent anxiety. At the same time, it will also create some factors that prevent you from really going to the toilet and entering the dream.
Without these distractions, if you dream about the toilet when you are in a hurry, you may actually pee. This happens to children from time to time. ?
2.? What happened during the day stimulated your brain.
The brain is more likely to store information about strongly stimulating events. You can recall that all you remember in your early years were events that made you feel very happy or extremely angry and painful.
Then at night, I dreamed that bugs were coming out of my fingers, probably because of a scene I saw during the day. For example, someone grabs a disgusting object or creature with their hands, which makes you feel surprised and disgusting. This feeling of panic can easily reappear in dreams.
Maybe you ate some food that upset you that day, and you were worried that something terrible would happen.
These stimulus signals will be received by the brain and expressed in dreams during sleep at night.
So if what you eat during the day makes you uneasy, through deformation, these anxieties will become worms and emerge from your fingers. Or as a kind of "detoxification", or let you see that your worry is really justified.
