The meaning of the dream is that nafs and Satan came in dream in the shape of snakes. The dream is warning that one should fear a lot from following whispers and misguiding of the nafs and Satan. You should tell your wife to study Behishti Zewar, Jazaaul Aamal, Fazail Aamal as well as Tuhafa-e-Khawateen (written by Maulana Mufti Ashiq Elahi Bulandshahri), or keep reading and listening any of these books at home. Your wife and other women will gain lots of benefits by studying, reading and listening these books, in-sha-Allah.
