Sydney Sweeney believes she was friends with a ghost.

The Housemaid actress had an imaginary pal when she was a child but "creeped out" her mom when it emerged the person she was seeing in the playground had died years before.

She told W magazine: "I think I've seen a ghost. When I was little, I used to have an imaginary friend. He would be on the playground at preschool. I would tell my mom about him. It turns out that he was someone who passed away before I was born! It creeped my mom out."

Sydney also claimed she is in control of her dreams when she is asleep.

Asked if she remembers her dreams, she said: "Recently, no. I don't even know if I'm dreaming anymore.

"I used to be a really vivid dreamer. I used to be able to control my dreams; I could lie there and orchestrate all the dreams that I wanted to have that night.

"In the last year or two, I haven't really been able to dream."

While the 28-year-old actress has a lot of fears, she finds the best way to deal with them is to face them head on.

She said: "There are a lot of things that scare me, but that doesn't stop me.

"Usually, if something scares me, then I'm going to do it. I have a fear of heights, but I jumped out of a plane and went skydiving.

"I'll scream the whole way, but then I'll want to do it again."

But Sydney's adventurous streak has seen her acquire a number of scars over the years.

Asked if she has any scars, she said: "I have a scar next to my eye. I got it when I was 10. I was wakeboarding, and I jumped the wake and I tried to do a 360, but the tip of my board came up and sliced me in the face. I had to get, like, 17 stitches.

"I tore my MCL dirt-bike riding, and the scar just never went away.

"Then I have a keloid scar. I got bit in Australia when I was filming the movie Eden, and I don't know what I got bitten by. It just turned into this crazy crater; then it scarred."
