hello that's my simple code for noting down dreams from python crash course practices 10.7

in this practice i tried to make a list of dreams instead of simply adding a value to key but dunno how to make a list . i did use list() but didn't work out well

how can i fix this?

 dream_makers = {}

active = True
active2 = True

message = "hello\n\t here we save all your dreams to remind you later or when you achive it :)"
message += "whats your name\nenter 'quit' to exit\t"

while active :
    name = input(message)
    if name == "quit" :
        break
    
    dream = input("what are your dreams")
    dream_makers[name] = dream
    while active2:
        sdream = input("do you have another dream to achive? \nIF NOT ENTER NO")
    
        if sdream != "NO":
            dream_makers[name] = dream.append(sdream)
            continue
        else :
            active2 = False
