In the sentence "Dreams are my reality," the word "reality" refers to what is real or true for the speaker.
This means that, for the speaker, dreams are not just fantasies but their actual experience, their world, or what they perceive as real.
It doesn't exactly mean dreams are my everything, but rather that dreams are what I consider real, suggesting that the speaker may feel more connected to their dreams than to actual reality.
It could be poetic, philosophical, or even romantic, depending on the context. 😊
