Nope, Ananda did not dream of the Buddhas. But he dreamt of 7
things and asked for dream interpretation from the Buddha.

The Dreams
Ananda had strange dreams one night, so the following day he told
the Buddha, "Oh Enlightened One, I had strange dreams last night,
and I hope that the Buddha can clarify them for me.
"I first dreamed that all the rivers and oceans were burned up by
great fire.
"In my second dream, the sun had descended and the world was in
total darkness. My head was supporting Mount Sumeru4, but I didn't
feel its weight.
"In the third dream, I saw the sangha putting on Buddhist robes,
but not following the Buddha's teachings.
"In the fourth dream, the monastic order did not wear Buddhist
robes, and they faltered among the thorns and difficulties of the
world.
"In the fifth dream, there were a lot of wild pigs rooting at the
base of a huge, lush candana tree.5
"In the sixth dream, young elephants trampled green grass and
polluted the river while ignoring warnings from the large
elephants. The large elephants could only go away to a place with
clear water and green grass. The young elephants later starved to
death because there was no grass to eat and they could not drink
the water from the river.
"In the seventh dream, a lion died, but other carnivorous animals
did not dare to approach to eat the flesh. Instead, worms came out
of the lion's body and ate its flesh.
"Why would I have these strange dreams?"
Then the Buddha replied with concern in his eyes. "Ananda, let me
explain them to you. In the first dream, you saw the fire burning
up the rivers and the oceans. This indicates that in the future,
monks and nuns will betray my teachings and start disagreements
within the sangha.
"In the second dream, your head supported Mount Sumeru. This means
that in ninety days I will pass away. All the monks, heavenly
beings and human beings will need your help to remember and pass
down my teachings.
"In the third dream, you saw monks and nuns putting on the robes
but not following my teachings. This means that after I pass away,
the sangha will give lectures on my teachings to large gatherings
of people, but the sangha itself will not follow my
teachings.
"You saw monks not wearing the robes, lingering among the thorns.
This shows that in the future there will be monks not wearing the
robes but commoners' clothes. They will abandon the precepts and
adopt commoners' lives, and they will also have wives and
children.
"You saw wild pigs rooting at the candana tree. The sangha in the
future will not promote my teachings, but will only look after
their own livelihood by selling statues of buddhas and holding
various services for commoners.
"Sixth, you saw young elephants not listening to the adult
elephants and later dying from starvation. This means that in the
future, new monks and nuns will not listen to the teachings of the
elder monks, and they will fall into purgatory after death.
"Seventh, you saw worms eating the lion's flesh. It indicates that
no other religions will destroy my teaching, but the monastic order
itself will be destroyed from within.
"Ananda, what you dreamt last night is the future of Buddhism," the
Buddha said sadly.
