I don't have nightmare about them but I hate them too. For a play I did years ago I had to make up as a clown. That was a weird thing for me but as I couldn't see myself once the makeup was on it didn't bother me, but I did inadvertently scare a small boy. Don't like circuses either after seeing the Moscow circus in Moscow.Knun Khun And Lucas I hate clowns they really do terrify me I have Nightmares about them
You say terrifying
I say scary
