I had a dream a couple days ago, I was chained to a brick wall and I was in a dark room. I was struggling to free myself but nothing worked. I gave up completely, then I started to cry out for someone to help me, then a bright light appeared in front of me. The brick wall started to crack and break down, I tugged on the chain and I was free. Then I ran to the light and then I woke up. Every time I think about it gives me goosebumps.

This can have a lot to do with your personal life. Dreaming is basically what your mind does to sort thing out. When wanting to know about what your dream means you'll have to know you and your personal life well. This is because dreams are symbolic, but mostly of your personal life and how you think. For example, a brick wall can symbolize a different thing to me than to you. So, naturally, I can't explain the whole dream to you because I am not you. Think about what all the key things in the dream mean to you and put the puzzle together.
Also, there are things that different people can see in different ways, so sometimes, we have to guess. For example, When I had a dream about death, he took a form of a sort of scare crow. Other people will see death as a sort of reaper or even a basic human. It all loops back to you and who you are.

Search for answers from google. They'll kinda help you with that.
Me I often dream of myself escaping from anonymous people I never saw from my life. Sometimes I also dream about my family chasing after me..and it's like when I run away from them..Im feeling like Im gonna die when they reach me.
I searched it on google and it says that Im escaping from my true self and that Im pretending to be someone I dont. Which is definitely true. Thats actually the problem im going through this crazy and weird personal life of mine :3 But still Im struggling to change this bad attitude.

I agree with >>2. This can have a lot to do with your personal life. I'm no expert, but a brick wall could mean you feel cut off from someone or something, and chains could possibly represent a trapped feeling?

>>3 fun fact: The reason why you see people you think you've never seen before in your dreams is because, even out of the corner of your eyes, your brain subconsciously memorized the facial features of strangers.
