The meaning of Saw, wood shavings in dream | Dream interpretation
Vision: Seeing or working with a saw: someone is out to humiliate or irritate you. Hearing someone use a saw: you are in need of a break—your nerves are irritated. Watching someone use a saw: somebody has disappeared and now you have to face the damage by yourself. Seeing a dull saw: you are working with inferior tools and won’t succeed. Seeing wood shavings: your work is creating useless “garbage.” See File.
Depth Psychology: The saw is a sign that you are overly critical and at times too cynical. Working with a saw: you need to solve conflicts and problems on your own.
The dream might also suggest you let go of a relationship. Sometimes the saw indicates sexual desires that call for attention.
