Cat question - she won't stop! Help?

Little Sasha kitty has been making these noises… they’re like half meows hard to describe but it’s been the past few nights. She’s been waking me up in the middle of the night (3,4am) and will do this for a half hour or so – while scratching at the door or random walls! She just wants to play but it’s not at an appropriate time. She’s 12 years old and her brother is lazy, and doesn’t respond to her calls.

Last night, it started at about 3:20am and I got out of bed, picked her up and she jumped out of my arms, then started running around my apartment. I had to put my headphones on and ignore her to go back to sleep. About 20 minutes later, she got into bed and finally fell asleep cuddling with me. Is there anything I can do to make her stop?? It’s really effing with my sleep (plus, it’s annoying).
