When you dream about a fridge, one thought is that it demonstrates your ability to keep your cool so you can make sensible choices in the long term.
It might also represent your need to preserve your dreams and goals if you feel them slipping away.
Perhaps you don't deal with things right away and always leave them to the last minute. Do you put things off? Especially important things? Maybe you don't want to deal with the responsibility of something right now. Have you been putting it off for too long? It might be time to deal with whatever you've hidden away at the 'back of the fridge'.
If you put fake food in the fridge, it's possible you are going to lie about something to someone. Alternatively, you may feel the need to pretend you have done something when you haven't or vice versa.
Another interpretation is that you have a cold personality and close yourself off to others, it might be time to let your guard down with someone you love and trust. On the flipside, it could mean that you are very transparent with others if the fridge was wide open. Are you showing off too much of yourself? Do you need to keep some things private?
If you were putting old food in the fridge, it's possible you have some strong, negative feelings about someone in your waking life. Is it worth all the energy?
If you were trapped in a fridge, maybe someone is trying to trick you- it might be wise to try and think hard about who this could be to stop them in their tracks.
A walk in refrigerator could mean that your relationship has become cold lately and you need to make a conscious effort to warm it up again.
If the fridge was full- it's possible that you are feeling wealthy in terms of your resources right now and have most things in abundance.
