The meaning of jack in dream | Dream Interpretation
Jacking up your car may mention the need to get underneath to see what is wrong with your vehicle or physical body. Thus, it may suggest that you look into the subconscious to discover hidden health issues. As it is used as a tool for changing a tire, a tire jack comments on addressing the emotional issues that have flattened you.

To dream of playing cards and holding the Jack of Clubs, a good friend; of Diamonds, a false friend; of Hearts, a true lover; of Spades, an enemy.
Dreams of a jack symbolizes support to elevate to a higher level, or a desire for assistance to repair what has been broken or to get out of a ditch. Perhaps this dream is showing you that you are a jack-of-all-trades.
If this is the case, then your dream is giving you the message that it may be time to focus upon that which you have the greatest passion and natural genius, or accept the fact that you are a renaissance man or woman, and diversification is your specialty.
