I'd say that the spikes are too short in duration to be a true representation of the actual bed temperature, so it looks like a noisy signal. Could be a bad connection or picking up interference from a stepper or it's wiring. Whatever the cause, it looks like a wiring issue to me.

Yes, looks like a bad wire. I had a similar issue with my extruder, and I found out that one of the cables was almost broken, giving a bad connection during extruder acceleration.
