Meaning of "Don't Be a Stranger" by Graham Coxon

The lyrics of "Don't Be a Stranger" by Graham Coxon seem to describe a person who is struggling with mental health issues or substance abuse. The repeated lines about taking a long time to think, having a dead brain, and looking scary with floating body parts hint at a sense of detachment from reality. The mention of not being a stranger to a shrink suggests that the person is avoiding seeking help for their issues. The imagery of a big rock dog eating an indie frog could symbolize an overpowering force consuming a smaller, more vulnerable entity. Overall, the song could be interpreted as a plea for the person to confront their problems, seek help, and not isolate themselves.
