Is it normal to feel nostalgic after watching a show which i used to watch in 2014?

Recently i have been watching this show Pritam Pyare Aur Woh by connecting Youtube to our TV. Its a comedy Indian Hindi show which shows ghosts but it's funny and not scary and it used to play on Sab TV channel in summer of 2014 but the show ended by mid 2014. I am again watching it on Youtube after 9 years. Its so funny that I am still laughing but I feel so nostalgic now as I miss those carefree days. In 2014, I was only 13 and was having my summer vacations from school while watching this show and I had no worries in those 2 months of Summer vacations whereas now I am 22 and feel scared about getting older and life becoming harder. The background music feels so nostalgic too. I also remember watching it with my grandma who used to live in my hometown Siliguri and she was living with us in Bangalore in entire 2014. That year we didnt go to Siliguri and Falakata so we used to live in Bangalore itself and watch it. Its crazy how much changed in just 9 years. I mean my grandma was still alive in 2014 and now she isn't (she died in 2021 due to covid). I miss those carefree days so much especially after watching Pritam Pyare Aur Woh now.
