What is the meaning in a dream of triangle

I dreamed on bermuda triangle

I fall in love with a boy I went to elementary school with. We're both teenagers. There's a bit of a love triangle but I want him. He acts uninterested at first but he accidentally gave me a bloody nose during a soccer game and then gets really worried and stops immediately to take care of me.

It was strange, to make it short, I was running from someone or something, and I realized somehow that I was dreaming, before I looked info about lucid dreams and know a few tricks to confirm you're dreaming, so I tried in my dream to look my hands, and I did. I asked myself, am I dreaming? And so a ran out of a door on an outer space and immediately looked back to see if that someone or something was following me, it wasn't. Is like I clicked in my dream and the whole dream changed. I saw as well that there's a device you put in your head before you go to sleep that lights a red beam in your eyes during the night, and you can see it when you're dreaming, so I looked up in the sky to see if I could find it but I didn't cause I don't have the device, but I remembered and looked up! Everything inside my dream... I knew I was dreaming. I was tryna figure out where I was and so I saw a door with blurry white letter written on it, I couldn't read it, but I saw a logo, I believe it was 2 triangles with stripes face opposite directions ( one up and one down) ^v ... what does that mean? I've been trying to look for the logo or symbol and I can't seem to find anything relevant...
