Friend kissing sleeping friend?

my friend said she is a light sleeper, but i rememeber years ago that we had a friend who was a coming out (sammy). and we had a big slummber party at a friends place. my friend tiffany (light sleeper) was laying on the floor near (Sammy). sammy was kissing tiffany on the cheeks twice then her forehead. if tiff is a light sleeper would've she gotten up and say "WTF"!?!?! she just layed there and sammy lay down by her.
