The trip you are on may be the life journey you are taking with your wife. I am not surprised she s there with you, as this change in you will affect her too. She may also symbolize the feminine aspect of your Self, the aspect that is intuitive and nurturing. The bleeding wound is on your left hand, the hand you favor and do most of your work with. Your creative hand.
Blood is life energy.
Losing blood in a dream often illustrates the lose of vitality and spirit through worry, fear, or anxiety. Just as the snake sheds its skin in the process of renewal, so you must shed your old skin to see the new, fresh growth underneath. The transformation is already complete on the inside. I hope you have support from your family and friends, so this change can be a positive experience for you. Some people say they never dream but these people are just not remembering their dreams.
