cat paws me before going to bed

I have a siamese cat. She goes to bed when I go to bed. She waits for me to turn off the bedroom light and waits to make sure that I'm falling asleep.
She done hops into bed with me climbs on top of me, usually on my legs(I sleep sideways). She then proceeds to "message" me or paws me in a rhythmic fashion before settling down to go to bed with me right on my legs or chest. She never does this when I lay on th coach or chair where she lays with me as well.
This only happens at night when I go to bed. Anyone knows about this.

She's kneading! This is a behavior from when they're kittens and they use this motion to encourage Mom to make with the groceries. It's one of many feline "terms of endearment", like head bumpies, leg rubbies and eye kisses.

That action is very much a compliment and means that she is happy. I can't say why she only does it at this time of day. But cats all have their own little routines and this must be hers. :D

How sweet! There is almost nothing better than being kneaded by a cat! It means she loves you.
