During Morrowind's Main Quest, of course, you encounter the poem 'The Seven Curses'. Most of the curses we know and saw in the game, but ight was never shed on three of them. The seventh curse, the Curse of Dreams, was happening during the main quest, and because the seventh curse was happening, we know that all the others were happening too. So, any ideas as the what the unknown curses are?
The Full Poem
...through the doors of the unmourned house
where scoffers scoff and schemers scheme
from the halls of the oath-breaking house
rings seven curses of gods blasphemed
first curse, Curse-of-Fire
second curse, Curse-of-Ash
third curse, Curse-of-Flesh
fourth curse, Curse-of-Ghosts
fifth curse, Curse-of-Seed
sixth curse, Curse-of-Despair
seventh curse, Curse-of-Dreams
