can someone explain this TSEM put to me

I bought a put
and the stock price went up

but the value of the put went up like 3x

was that from the market shitting?
was that because it's closer to expirey?

why did the price go up on the put even tho the stock price went down?

I thought it'd make money if it got to 40 DoE
but be worthless if 41 on DoE
would it being 36 on DoE make it worth less than 40 on DoE, it's a 40 dollar put contract...

just explain why it went up in value thanks

can someone explain
how my puts on a company went up in value
even tho the company stocks went up???

something to do with expirey or the rest of the market shitting?
