After watching “A Strange Vessel,” the mere concept of sleep was the last thing on my mind. When I did manage to get some shuteye, I had the oddest dreams—that’s how much the latest episode of Channel Zero: Candle Cove (CZ:CC) impacted me. “A Strange Vessel” is a wonderful follow-up to the events from “Want to See Something Cool?” in that it reveals surprising twists to the main story lines.
