Wife seeking husband's permission to go sleep

Q: At 6pm I feed my family. My husband comes late so he eats at 8pm earliest. I try to have my kitchen clean by the time I go to bed at 9pm or 10pm. I check on my husband. We sleep seperate (not ideal but it is what it is). I say goodnight to him and I go to my bed.

Sometimes he tells me that I am not allowed to go to sleep unless he gives me permission to go sleep? Am I disobedient if I go sleep?

This statement makes me feel like a slave and not like a wife.

Is this the level of obedience a wife must give to seek permission for basic human needs?

Marrying two sisters

Q: My husband manipulated my sister and got married to my sister without giving me a divorce. When my sister got to know that their marriage is not valid after a year, she got married to another man. That man left my sister beacuse he thought she did nikah on nikah, but that was not the case.

Wazifah for repelling bad thoughts before sleeping

Q: My grandmother who is a widow has asked me to ask this particular question to you:

She has asked for any wazaif or any specific azkaar to be recited as she is saying that before bedtime in the night she gets some bad thoughts. She said "aise taise galat galat khayaal aate rehte hai"...I don't exactly know what she means by it but she regularly recites prayers and azkaar and Quran before bedtime. Kindly help with some azkaar/wazaaif.
