The Purge

Do you purge your body of things in dreams?
If so, what do you purge? (if you don't mind me asking)
Is it connected to or does it remedy issues in your non dreaming life?

Last night I pulled a seemingly endless amount of a gummy substance from my tongue. When finally it was ripped free, there came a flood of memories of doing this recently (in dreams). It is a thoroughly disgusting experience. Often, the 'after mass' is alive to some degree. Very reminiscent of dreams of my teeth falling continuously out by the hundreds.
Combined with the plethora of school dreams, I believe the gummy tongue has to do with choices I'm flirting with in regards to my educational path. My mouth is cluttered conversations it no longer needs but once cleared I haven't the collection of words needed to convey new thinking. I don't know if that even makes sense.

I just wondered if such purges are actually helpful to some degree outside of dreams.
In dream, I very definitely should reality check if I encounter gummy tongue again.
