strange dreams involving animals

1- the setting is in a deserted area, there are couple mountains and a tree...it looks like a place where lions would hang out...I was a young lion just looking around... it felt like I was staring into nothing then a pack of wolves show up and they try to attack me then I fight back...while this is happening everything in dream starts to slowly turn pixelated, like some matrix looking setting...then I wake up....

2-the dream starts with a blank black background with white words in text and the only word I can make of is "greatness"...then I somehow know there is suppose to be a gathering of sorts by this ocean... im not really sure if I knew it were to be dolphins and seals...I get to this ocean and feel disappointed because they are not there...I thought to myself is it because the water? is the water polluted?...then in a blink of an eye, it seemed like 100's of dolphins and seals started coming towards my direction in a wave...it was an amazing thing to see and I was so overwhelmed by the happiness I started to cry...then it cuts to another scene where I see a fence and people coming out through the hole in the fence...all these people were running towards the ocean to see this amazing event...the last ones to come out the fence was a black dog and a person...they both didn't like the fact that they bumped into each other coming out the fence but realized quickly they shouldn't be mad at each other and there should be peace and lets go see this event together...then I wake up...

3-i had this dream today...these are the parts I can remember clearly...I open a door in front of me and there are people I am not familiar with except a girl in front of me who I believed to be the sister of a kid I used to hang out with when I was a kid...this kid was not a good person at the time.... but anyway next to her is a beautiful pitbull dog and she is holding a very tiny puppy that is of white color...I take the puppy carefully from her and go back in the door I came out from and started to play with the puppy....the puppy is very active, bursting out in speed and jumping onto me. I was very happy and laughing...I hold the puppy and head back to the door so I can give the girl the puppy back...as I get near the door I started to get a little nervous that the puppy would scratch me as the puppy was anxious for me to let go so I let go and the puppy runs to the door and goes out through the crack in the door...I was very nervous and worried for the puppy because it was so tiny and so white that people in the room would not be able to see it and end up stepping on it...me and the girl tried to make sure to find the puppy, we are looking everywhere...then I wake up.....

anyone had similar strange dreams? and know if there are symbolism to these dreams? thank you
