Is it ok for two single people to cuddle up in a bed together, but not be ual?

I stayed round a friend's place saturday night and there was a single girl with us, and when it come down to deciding where to sleep and whom with, we decided that me and her sleep together in same bed. We were talking most of the night and i felt a connection between us, and we carried on talking when we were laying in bed and i then initiated her to snuggle up with me, and she did. Is there anything wrong with this? We didn't get intimate with each other, apart from the snuggling up and she laid her head on my chest.
