I don't do it on a regular basis but occasionally I feel like I have the same snippets of thoughts bothering me and it feels therapeutic to put them somewhere outside of myself - temporarily at least. It's dodgy because there are usually people around who you don't want to be exposed to the truth of things so it's a guilty secret and everything gets destroyed later anyway.

It helps me at times. Relaxes the mind. Helps me acknowledge and make sense of feelings.
