Because dreams are simple, they can only provide ideas for your own analysis:
If you are engaged in the gasoline industry, it may be that high oil prices have brought you this dream.
It may also be that you are not very satisfied with the current working environment or the job you are about to face. A place full of petrol tanks also represents a kind of backwardness.
It is also possible that you have recently encountered some kind of crisis, like a petrol tank that may explode at any time.
Dreams are a reflection of real life. If dreams are written in detail, they can be explained more clearly.
