What do you think this dream means?

one night like maybe a month or two ago, i had this dream where i was at the beach and there were these reallyyy high bleachers (like in a stadium). there was a bunch of people sitting in the bleachers and i was sitting with my dad at the top. the tide was up, so the water was right up to the bottom of the bleachers. i kept telling me dad i wanted to go down to the water but he kept telling me no. finally i went down there without him and then suddenly i was afraid because i knew the water was reallyyy deep. then the tide went down and i started walking down the beach and looking at all this sea gl laying on the ground. also, i remember that the sky was dark grey and cloudy. thats all of the dream, but the weird thing is that a couple nights ago, i had that exact same dream, but there was no one in the bleachers and my dad wasnt with me. also this time the sky was still cloudy, but it was sorta orangy like sunset and much more pleasent. i seemed more calm in this dream, but other than that it was exactly the same!! what could this mean, im so curious!!! i appreaciate all your ideas and oppinions! :D
