I saw myself (from above) in an ocean with many others floating/swimming nearby and far. I remember talking to a lady about it who told me that I was in a much smaller water-body, and she told me that there's an even bigger water-body in which many more people swim. I remember myself planning for swimming in this water-body for quite some time.
I remember myself surrounded by many people in that ocean size water-body. Initially I was surprised to see myself there; I look around. I saw the nearest shore, so I started swimming towards it.
