Dreaming of a snake

Asalamualaikum w w. i had a dream about a snake but it was a very light colour like an albino snake it was just lurking near me and then we were in like a boat or a pier or something (like standin just at the water) the water was absolutely blue and so clean and beautiful and my eldest son jumped in to swim and then i screamed at him to come out because this same snake suddenly came out from under the water . It didnt touch him or anything but it was moving very close to him in the water! Muftisahib i just want to please know what does that mean? Allah reward you and your family abundantly jzkl khair
