Who was the African queen who said that any of her subjects that appeared in her
dreams would be executed?

Hi keithb,

The queen you are looking for is Queen Ranavalona, of Madagascar (the
"wicked queen").

"Queen Ranavalona of Madagascar ordered that any of her subjects who
appeared in her dreams had to be executed."

"Queen Ranavalona of Madagascar decreed that if any of her subjects
appeared in her dreams, they would be killed."

Madagascar:
"Immediately after Radama's death in 1828, his widow (Queen
Ranavalona) took the throne. Referred to even to this day as the
wicked queen, Ranavalona forced the missionaries out of Madagascar,
and executed her subjects with a zeal never before seen in this land."
