I was terrified of loads as a kid. My sibling was the tough ballsy one and I was the wimp.
The flying dog in never ending story.
The rain (!) I would worry it wouldn't stop and we would all be flooded. I used to write notes to God asking him to stop the rain!
Car or house alarms, I had a fear they would never stop. I still actually have this now if our house alarm plays up in a power cut.
Our family cat attempting to come and sit on my knee. I was scared she would do that thing where they pad around for ages before sitting down and she would hurt me. Kid you not, if she jumped on the sofa i would grab a cushion as quick as a flash to protect myself
Car washes, I thought they would malfunction and I would be stuck in there forever.
Walking over bridges.
The millennium. Thought we were all gonna die.
The video for stay by Shakespeare sisters.
I had a lot of moments as a kid where I thought if I did something, nothing bad woulf happen. So I would make myself tell my parents they were the best, tidy my room etc.
