that is normal. Your issue was a glitch that a reboot cleared up. If you hold the power button for a few seconds until the curtain comes down, you will get a full shut down (not sleep) followed by a boot at your next start up. good thing to do regularly...like your last shut down for the day, etc.
Or hold it longer and get an immediate reboot.
