Three Little Girls, Three Beached Whales, and One Journey

I was told that my father was not my real father. My real father was in the neighboring town. I literally began to RUN to find him. I was tearing through the city areas to find him. But, on my way, a girl that was really young with blonde hair told me stop. I wondered if she was my younger self. I didn’t stop, she was creeping me out. She started following me and telling me to stop. As I ran, an older version of her, maybe around 10, began to do the exact same thing after I passed her. Then, a 15 year old version of the girl began to follow me too. I was so freaked out, but I just kept running, and I would check behind me to see if they were still there. I ran to a little beach shack (though it seemed to still be in the city surrounded by townhouses) to meet my real father, who ended up being my friend’s dad. They lived in the shack near a beach that was behind all the houses. I think I spent the evening with them. We went to the beach at night, but these three whales started washing up on the shore. They were dead, and they had strange patterns on them. It was unnerving, so we went back to the shack. I vaguely remember something else happening… I think we went to a drive-in movie? Or we were going to the bar? Either way, the number 3 seems like it was prominent in this dream.
