Put your body in all the places you were. If you were laying in bed, lay in bed. Move your arms around. “If I was an iPad and I wanted to disappear, where would I hide?”
If you were sitting in a chair, sit in that chair. Move your arms around.
My phone often ends up stuck in a crack between my bed and the wall.
I think we unconsciously make very slow free throw baskets with stuff because they always end up in awkward cracks and things.
Favorite hiding place for the remote is under the chair, JUST BEHIND the front leg where it’s entirely invisible, and when you scoop your hand under it quickly to search, your hand doesn’t go there.
So yeah. Good luck. It’s findable.
