I dreamed that three men in black grabbed me and twisted my arm. It hurts. It's a little dark as night. What do you mean?

Due to the lack of information, the interpretation of dreams here is biased towards speculation, please judge for yourself, thank you.

I have an uncertain dream.

Three men in black twisted my arm: referring to some thoughts twisting with their own actions;

Very painful: it shows that your mobility has been hurt by this idea;

The sky is dark as dusk: it means you are in an uncertain mood;

In other words, in my own thoughts, there are thoughts that are "distorted by my own actions", which may be self-denial, fear of putting them into practice, timidity and so on. These thoughts are intertwined with my own actions, hurting my actions and making me afraid to act, so I feel uncertain.
