what does this dream mean.?

when I had open heart surgery in 2014 I had very interesting dreams #1 I am walking through a forest with a sword in my hand and I go up against these things but there aborted human and animal fetuses and they have sword too we go into mortal combat .#2 I drive into a multi level parking garage I drive up to the top then back down ,up to the top and back down then drive out and around the garage counter clock wise then reenter the garage and do it again {up to the top and back down several times} then drive out of the garage and go clockwise around the garage.#3 I,m walking down the street of my home town naked in the snow and crossed the street and start making left turns walking around the block ,crossing the street and making left turns walking that block of buildings then cross the main street and do it again but with right turns .....what does this mean?
