This one will only work if you sleep under a duvet (or comforter with a cover) and
if you sleep with a partner.
Method, you have to go to bed earlier than your other half. Turn the duvet (comforter) upside down so the fasteners are at the top instead of the bottom. Then wriggle into the cover with the duvet on top of you. When your other half comes to bed and tries to give you a cuddle they will not be able to find you! Apparently works and leads to lots of giggles.
If anyone tries it out please let us know if it worked.
