It’s hard to go back to these childhood memories. My parents let me watch some creepy stuff as a kid. Bug is one that gave me nightmares.
Another that had me sleepwalking and freaking out was
Attack of the Mushroom People. I got it on netflix recently and decades later I see it for what it is. It’s a commentary on drug use and addiction. The mushroom people are not even really threatening, they’re basically stoned. But as a young kid I wandered around at night afraid that there were musrooms growing in my bed. I didn’t eat mushrooms until I was an adult.
