بسم الله الرحمن الرحيم
(1) This dream is a hope for good. If your mother is alive then you keep on supplicating for her longevity and if she is dead then pray for her forgiveness. Read mansoon duas before going to bed and develop the habit of sleeping with wudhu.
(2) It is nice dream, ma-shaAllah. You shall be blessed with prosperity, in-shaAllah.
Allah knows Best!
