Yes, dream interpretation is indeed in the scriptures.
Note, however, that Jacob, Joseph, Daniel (I think he too interpreted a dream?) and the other dream interpreters of scripture did NOT run off to consult nonsensical ‘dream interpretation’ books in order to do so. And note that when Pharoah DID consult his ‘experts’ in such matters - his wise men and magicians - they could offer him no guidance.
Instead the successful interpreters sought and received God’s guidance directly, relying on His wisdom alone and no ‘dream interpretation books’ or anything else so patently ridiculous.
In fact Joseph, in all humility, claimed no special power to interpret dreams at all - " ‘I cannot do it’, he said, 'but GOD will give Pharaoh the answer he desires" (Gen 41:16).
So if you wish, go to God in prayer and ask Him, if it be His will, to reveal the meaning of your dreams to you, if they indeed were messages from Him. Be aware that the vast majority of dreams assuredly are not, but merely the products of our own brain when at rest and repairing itself as it does in sleep.
Don’t waste your time consulting books that cannot possibly do what they claim - how can a dream about a particular thing mean the same thing to all dreamers after all?
Surely a dream about snakes, for example, would mean totally different things to someone who has been through the trauma of snakebite as opposed to a snakehandler or scientist who studies them and appreciates them, as opposed to someone who simply dreams about 'em because they have recently seen a movie like Anaconda or Snakes on a Plane.
For what it’s worth, yes I do think it’s a sin. It’s allowing man - the writers of these books - to usurp a role - spiritual guidance via dreams - which should be reserved to God alone.
