You are not being unreasonable at all.
Block and do not engage.
When you live in an adjoining semi detached/terraced house you have to expect some noise.
If you don’t want noise - live in a detached house.
I have a neighbour like this in her 80’s joined to me. We are very respectful, try not to make much noise, yet I can hear her TV blaring, her very loud washing machine spinning at midnight and (probably to wind me up) - she’s put a very loud chiming clock on the front bedroom wall which I hear chiming every bastard 15 minutes.
She’s constantly banging on the wall / playing her radio on full volume.
I tried being polite but after 7 years of her bat shittery I realised you can’t ration with people like this. They are disordered in their thinking.
She would constantly email / phone me (our builder gave her my details once). After many ‘caps lock’ shouty messages, I warned her I was blocking her and would not be picking up further messages (which I did).
She did start taking photos out of her front window on her iPad of me / my DH coming in and out of her house, which I reported to the police and they put a community support officer on it and it was logged.
She’s now started on the other side.
Sad really as she’s lived in the street since 1943 but has completely alienated herself from everyone due to her moaning.
My advice - ignore, ignore, ignore.
Good luck 🤞
