I’ve Clearly Been Watching Too much TV Before Bed

I had a dream that they found forgotten in some vault on the Paramount lot an entire 4th season of Star Trek (TOS) that never aired. Episodes included a 2 parter where Khan and 2 of his rivals escaped from their banishment on Ceti Alpha VI and each took over a planet’s civilization, waging a massive interstellar war with Kirk and the crew of the Enterprise caught between them. There was also a 3 part story arc that was basically a retelling of Macbeth with Klingons (only they were the wrinkly forehead Klingons from the movies and TNG era, not the guys in bronzer from TOS era). There was also an episode where they found floating in space a disembodied head that came to life when they beamed it aboard. The head had Q-like powers and made the crew’s life hell until Kirk agreed to help it find all it’s missing body parts and reassemble it.
