Interpretation of dreams: I dreamed of looking for the key in the sewer!

Dreaming about looking for something is generally a search for past memories. Because when we were very young, we often lost things and often struggled to find these things (especially important things like keys). These memories are generally deep, so we usually have such dreams later.

Your dream is basically some fragments of childhood memories, but it is also mixed with some other factors, such as looking for it in the sewer. Here are some other references. Generally speaking, when you dream that something has fallen into a dirty place, such as toilets, sewers and garbage dumps, when you want to rummage, it is usually the influence of the current external environment. You are disgusted and contradictory to the present external environment, but you have to accept it because of important personal interests.
