Dryer dream meaning is explained below using 4 different sources. Each interpretation is shown with its source.

Interpretation 1 — Dr. Mıchael Lennox

A dryer removes the moisture from clothes that have already been cleaned. In this way, there is an element to this symbol that relates to the evaporation of previously powerful emotional experiences. Those experiences may in fact have made you feel dirty or unclean, so the symbol of the dryer has within it the implication that something has recently been cleaned or cleansed.
