Some dogs have abnormally excessive, even violent movements during sleep.  They may lift their head and propel themselves across the floor with running movements.  They may attack inanimate objects.  In contrast to a seizure, dogs can be aroused during these episodes and awake with no confusion or incoordination.

This syndrome may be similar to a sleep disorder in people called REM behavior disorder.  The drug clonazepam is often successful in affected dogs and people.
