Dream about trying on jeans is about repressed aggression and anger. You are not challenging yourself. Some repressed memory or feeling remains unsettled and is threatening to emerge into your consciousness. This is unfortunately a warning for your idealized version of someone you know in your life. You need to get a better handle on your life situation.
Trying on jeans dream is an evidence for your pent up anger and hidden aggression. You need to proceed with care and caution. You are not focusing on the matter at hand. It states your arrogance and that you need to tone it down. Your laid back attitude will cause you to miss out on life’s opportunities.
If you dreamt about trying on jeans:
Today you might find it necessary to turn down an invitation to a social event, and the host might for some reason seem offended. Your friend is probably overworked and stressed and apt to overreact to just about any situation. Relax a little. Explain things to your friend and then propose that you get together at another time. That’s all you can do now.
