Functions are named as I would expect them, when I read the name - I know what is happening.
Same goes for variable names, most of the variables are properly named
Your code is very readable, I didn't even have to have any explanation to understand what it is doing - keep it up!

Extract more functions

The following can be generalised to a separate function and hence you can have the same logic for other main functions.
if choice in answer_A:
        print("The garlic did stopped the vampire but it did not stopped it's blood thirsty bats.\n\n RIP")
        return "Gameover"
    elif choice in answer_B:
        print("This is not hide n'seek \n\n RIP" )
        return "Gameover"
    elif choice in answer_C:
        return "village"
    else:
        print('Invalid input')
        time.sleep(1)
        option_castle()

Printing options can be generalized as well - not only to make the code easier but so you can easily expand your number of options - read about args.
print('''    A. Take the garllic to scare the vampire.
    B. Hide
    C. Escape from backdoor.''')

Variables
"Gameover","intro", "cave" etc should be extracted to variables so you can easily translate/refactor it later.
Generalizations
You might want to extract reading user input and writing the output to a separate class/function (class is preferable). This will give you opportunity to port your game to UI other than console.
nits

Usually, it is a good practice to use  if __name__ == "__main__" (see here) when you want to run script directly (play())
Variables y and x could be better named to indicate what they contain
Extract 1 in time.sleep(1) to a variable. You might want to change it later and if you would have more functions, it would be annoying.

 Q:

Inference in typed lambda calculus theories

I'd like to do automated inference, say solving word problems or reducing to normal form, in an equational theory of the typed lambda calculus (with product and unit types). Equivalently, in category-theoretic language: I'd like to do inference in a cartesian closed

 Extract more functions 

 The following can be generalised to a separate function and therefore you can have the same logic for other independent functions. 
 if choice in answer_A: 
         print("The garlic did intercept the vampire but it did not stop it's blood thirsty bats.\n\n RIP ") 
         return " Gameover " 
     elif choice in answer_B: 
         print("This is not hide n'seek \n\n RIP ")

     elif choice in answer_C: 
         return " village " 
     else: 
         print('Invalid input') 
         time.sleep(1) 
         option_castle () 

 Printing choice can be generalized as well - not only to make the code easier but so you can easily expand your number of options - take about args. 
 print ("'     A. Take the garllic to daunt the vampire. 
     B. Hide 
     C. Escape from back door."') 

 Variables 
 " Gameover","intro ", " cave " etc should be extracted to variables so you can easily understand / refactor it later. 
 abstraction 
 You might want to extract learn user input and writing the output to a separate class / routine (class is preferable). This will give you opportunity to port your game to UI other than console table. 
 nits 

 normally, it is a effective practice to use   if _ _ name _ _ = = " _ _ main _ _ " (determine here) when you want to run script immediately (play ()) 
 Variables y and x could be well named to indicate what they check 
 Extract 1 in time.sleep(1) to a variable. You might desire to change it later and if you would have more functions, it would be annoying.
