I can't find a Spotify-created playlist - has it been deleted?

[Czechmishaout]

Hi all,
I had a top favourite Spotify playlist, which was always one of the first ones in the Sleep category, called "Lost in Clouds". I listened to it for hours, almost every day, I loved it so much. But, in the past few days, I noticed I can't find it anymore. I searched for it by name, on Spotify's profile under their created playlists, tried everything I could think of, but I can't find it. I can't remember names of any of the actual songs, though.
Does Spotify randomly delete playlists or am I being daft?
