Lost: Represents the dreamer's confusion and bewilderment.
Walking: represents a aimless lifestyle.
Find the way home: home represents a kind of psychological dependence, and road represents a process. This sentence symbolizes the process that the dreamer seeks psychological dependence because of the wrong choice or confused status quo.
The misty world: represents the confusion in the dreamer's heart.
Familiar Mountain: In the dream about the road, things beside the road represent what the dreamer experiences in reality. If a mountain appears on the road, it means there are obstacles that are difficult to climb. If it appears nearby or far away, it is meaningless or represents the dreamer's desire for familiar feelings (if the dreamer is in a foreign land).
PS: It's hard for me to connect "familiar mountains, I hope to be lit up", but the dreamer said so, so I can understand it for the time being.
Hope to be lit: this sentence is too abrupt, I just want to try to guess. The object of lighting may be many things, such as lighting yourself, which means that the dreamer wants to get rid of this confused division. Igniting hope represents the dreamer's desire to find psychological dependence after finding this confusion unbearable. Ignite everything: it represents the dreamer's deep heart and extreme dissatisfaction with the status quo.
