Not always, it depends if lets say you know each other for a long time MAYBE she does, but at other times she could just see you as a friend
Not necessarily. People may feel comfortable enough to sleep on someone's shoulder without having romantic feelings towards them. It could just mean they trust and feel safe with you.
Yes, it appears that she likes you.
That she likes him. It's not necessarily a invite to sex.
I think it means she trusts you and you guys are really close or she likes you!
it means she wants your attention slightly but not all of it
No.
If you are dating or hanging-out together then it could mean she likes you, but it's not enough to say "yes this girl likes you a lot because her head is on your shoulder." If you aren't dating then ask her out on a date and if you are dating then you know she already likes you a lot!
no it means hes lazy or likes to sleep
Maybe, or simply that she trusts you which could mean quite the opposite.
It could mean that he likes the girl that likes him. :)
That means the boy likes the girl What elsa does that mean.
Maybe, or maybe he thinks you are just a good bit of nookie.
yes
it means that he likes u very much and he feels likes to take it to the next level
