I wrote a minor GNU Emacs mode for writing surreal texts, that is, stream of consciousness writing.

Ideal surreal writing happens when:

1. One does not stop oneself from writing the words that come to one’s mind.
2. One does not deletes or replaces the text in part or in whole.

So this mode is designed to stop oneself from breaking rule number 2 - deleting or replacing already written text. It aims to disable movement, deletion, and replacement commands.

It is also incomplete. Anyone who knows how to complete it, please send patches.
