All I remember wis having crossed over into some portal and then bean in a boat but being under water and there was a huge fish swimming past me.
The dream may suggest that you have a desire to explore new and unknown territories in your waking life. The portal represents a transition from one phase to another, indicating that a change may be coming up for you. The fact that you're underwater can imply that you're feeling overwhelmed or subdued by your current situation. Nonetheless, the big fish that swam by you might represent a symbolic message or someone/ something important coming into your life. It could be a sign of prosperity, abundance, or success. Overall, the dream could be encouraging you to be receptive to new opportunities that may come your way, even if they may seem daunting at first.
