I dreamed that I was being laughed at by others while swimming in the water.

Swimming: indicates good health. Sometimes it has sexual connotations.

Swimming in the sea by yourself: indicates good health, energy, and a desire for challenges. Be brave enough to open up new situations at work, and dare to try things again if you didn't do well before. You can also be proactive in love...

Swimming in the river by yourself means being strong.

Swimming across the river: it indicates success in career and fame.

The wife swam across the river: suggesting that there will be estrangement between husband and wife.
