Sweet dreams and hope to see you soon
beau reve but with a circumflex over the e in reve.
Un beau rêve = a beatiful dream / a nice dream, a sweet dream.
(I wish you) sweet dreams
I'll talk to you and soon.
"et à bientôt" = "and see you soon"
a bientot sounds brief and informal, but it is correct
"très beau et" means "very beautiful and".
"et sera à la maison bientôt" means "and will be soon at home / at the house".
vieux et beau - vieille et belle
Say "A Bientot"
It should be 'beau rêve' or even more more usual is the plural - 'beaux rêves', as in English. It means good (or sweet) dream.
"She is very beautiful and she is a dream"
