Dream about large yellow snake is a symbol for problems and issues of losing control. There is a situation where you just need to grin and bear it. You need to concentrate and focus on a situation that has long been neglected. The dream is a message for your emotions and how cold and rigid you are behaving. Your mind is not clear.
Large yellow snake is sadly your current condition of poverty and misery
You are being sidetracked by counterproductive activities. You need to exert more control over aspects of your life. This dream is a hint for your maternal instinct and your desire to provide for and support your dependents. You need to shield others from your drive and ambition.
