The same thing happened to me with a few memories:

• People turning into blocks and interlocking to form a city. It turned out to be Unico: Island of Magic.
• Some evil guy crawling into a painting, and something about hair growing. This was a fucked up movie called The Peanut Butter Solution. This one legit scared the shit out of me as a kid and I had nightmares about it.
• A guy being surrounded with evil looking puppets. This was a stage show called In Search of the Wow Wow Wibble Woggle Wazzie Woodle Woo. I didn't remember this one until the youtube channel RedLetterMedia made fun of it.

These must have just been random VHS tapes my parents got in some bargain bin. I have no idea how we got them or what became of them.
