I'm just looking for someone to review this and see if it all works, here you go.
I must mention that once you start this code adventure, all answers to questions must be in single quotes (i.e. ') and lowercase.

Welcome to CodeReview. Your program is a fun start to programming, and Python is a great way to learn. For the following topics, I'm going to trust your ability to google, but if you can't find the appropriate documentation leave a comment and I'll add some links.

Avoid globals

Sometimes globals can be useful, but more often they hinder a developer's ability to maintain and debug code. It's a better idea to group related variables together into a class. This applies to the following variables:

items = ['backpack','deagle','stick','mushrooms']
stupid = 0
backpack = 0
deagle = 0
stick = 0

Avoid stringly-typed objects

These things:

items = ['backpack','deagle','stick','mushrooms']

are strings. But in this case, it's not very good practice to handle them as strings until they need to be presented to the user. In other words, in this statement:

if "mushrooms" in ch4:

What if you misspelled 'mushrooms'? You wouldn't know until halfway through a program run; in other words, string-typing hinders static analysis, among other problems. One solution to this is to have an enum: a kind of object that can take only one of a set of mutually exclusive values. In other words, an item can be only a backpack, or a deagle, or a stick, or a mushroom. Python IDEs are better able to perform static analysis on this, and programmers make fewer errors when following this strategy.

Indenting

For legibility, you should ensure that each additional level of indentation only introduces 3-4 characters - pick one and stick with it. This:

 def items1():
 global items

is too far in for the comfort of most developers.

These aren't assignments

 deagle == 0
 backpack == 0
 stick == 0
 stupid == 0

They're comparisons. Assignments need only one =.

Input comparison

This:

if ch3 in ['y', 'Y']:

is more easily done by first converting the character to lowercase, and then comparing it to a single character; in other words:

if ch3.lower() == 'y':

There are a few points I would like to add ontop of the feedback already given by Reinderien.

Remove nested functions

There is no good reason to define house(), deeperhouse(), etc. inside of game(). If your plan was to hide them from the user in this ways, you have probably chosen the wrong language. If you intend to indicate that these are not to be used directly, prefix their name with a leading underscore _house(). This is a common convention to notify others that these functions are not intended to be used by them and are subject to change/removal/... without further notice.

Also think about how you use these functions. Basically, your game's "flow" is encoded in them by calling deeper and deeper into other functions without ever returning.

Break lines to improve readability

Your text message come in super-long lines of text. Most text editors support automatic line breaking or soft wrap to cram those lines to the available screen width, but some don't (like the code preview here) or are deliberately configured not to do so. So be nice and break your lines if they get to long.

Python's official style guide recommends 79/80 characters as maximum line length, although most modern IDEs and their style tools let you get away with about 100 (without manual tweaking) before getting upset.

Python allows you to do this within the parenthesis of a function call without further line continuation markers.

Applying this to house(), your code could look like this:

def house():
 print("You walk inside slowly, nearly crying because you are such a baby")
 print("You look around the building, there is a selection of objects on the ground, "
 "a stick, a backpack, and a deagle with 100 rounds next to it. oh and lest we not "
 "forget, some mushrooms, picking them up will make you eat them immediately.")
 print("What do you want to do now?")
 items1()
