My girlfriend woke me up the other night cause she heard a noise. I went to check and it was nothing. Then she woke me up again, she said she heard a noise like knocking on a door. Last night same thing. Then she realized that while I am sleeping I am fingering the side of the bed. She thought I was scratching it but no, she is sure I was doing the motion of plucking a bass. So maybe I need to see a shrink. Do you play bass while you sleep? Sleepplucking?
