I would read or write a story about a young boy and a boat and make it a nice, pleasant dream, see if I could affect the situation that way.
If I couldn't effect a change and/or in any event, I'd get a doctor's appointment and have a complete physical, blood and urine tests, etc. to see if there is something physically wrong. It could be you're "drowning", aren't breathing right or have some other medical issue that needs addressing.
