Gas in a dream, especially poison gas, can represent intelligence or knowledge that is used in a dangerous way.
If you dream about gas, your dream can be a warning that you should be careful about how you deal with knowledge that you have gained.
Could you have heard some malicious gossip about someone you know, or have you heard some troubling news that could cause someone emotional pain?
Think carefully about what you say and how you say it.
If you dream that you are being suffocated by poison gas, you may feel that information that you have gained is trapping you and preventing you from moving forward in life.
Dreaming that you flood a room with gas can indicate a desire to have control over the beliefs of others.
A dream that you are unable to turn on the gas in order to operate a stove or oven can be a sign that you have run out of energy.
