okay my whole life i have had dreams not all of the time but they pop up through out my life.

my most recent nightmare i had was i was in an aquarium with an orca i was petting it at first and then it grabbed onto my leg with its mouth for a minute.. i felt like i was drowning, i couldn't get my leg away there couldn't really keep myself up.. the orca did not drag me under sord of like warning me he was gonna hurt me if i didn't get away.. he let me go.. i swam of to the ledge that was blocked on the sides. one of the ledges the orcas could beach on, and it came after me on the ledge and just started swinging its head around with its mouth open showing its teeth.. it grabbed me and drug me back into the water and just kept throwing me everytime i would get to the ledge it would come over and throw me away from it. i don't remember the rest.
i dream of them in aquariums a lot and they are mean to me, nearly always being attacked.

but i have had dreams of them in the ocean, last year this one stands out the most.. i was all by myself sitting on a doc in the ocean.. i could see a group of orcas swimming in the distance, i jumped off the doc and got in the water and strated swimming, it was late afternoon.. and the sun was like a reddish color. i could feel them under my feet just swimming... one swam up to my face and let me pet it i put my forehead on his nose like we were bonding, he was real nice to me he pushed me back to the doc real easy and gentle.

these dreams are very odd to me, because i live in ohio and only been to the ocean maybe 5 times my whole life. and i been to seaworld a lot.. but i really don't understand these dreams... i feel in the dreams, it scares me when i wake up when they are bad. i can actually feel the orcas in my dream what they feel like, the water, there power and movement because of how big they are.
someone please tell me what dreaming about orcas is all about?
