My clutch pedal started acting weird today. I have a 2004 six speed. I went to press the pedal and it went straight to the floor, and didn't come back up. The clutch isn't opening. I also had a few random dash lights go off (windshield washer fluid level, seat belt indicator). The issue went away after a few minutes. The fact that it isn't constant and the symptom correlates with the dash indicators makes me suspect an electrical issue somewhere. Has anyone experienced this before?

My first thought was the clutch master cylinder but the electrical symptoms make me think not.
