You're missing a few : after your IF statements. Also, you can't have an IF or ELIF statement with nothing following it:

name = input("Type your name")
print("Welcome", name, "to this adventure!")

answer = input ("You wake up, and are laying on a bed.(get up/stay asleep")

if answer == "get up":
    print('You have to put stuff after an IF statement - It cannot be blank')
elif answer == "stay asleep":
    print('You have to put stuff after an IF statement - It cannot be blank')
else:
    print("You stayed asleep and had no adventure, and lost.")

You need to add a : afterwards.
I'd recommend looking this up before adding a post about it.
