If all the warning indicators flashed, starting with the seat belt, and the fuel, MPG, guages drop to zero, especially if you are using the wipers, and come back it is a marginal power supply in the cluster. It also cold be an indication of the alternator regulator or diodes, being weak. Do a search on "flashing indicators" the cluster can be repaired, or there was a fix to replace a capacitor.
