Dream about drinking oil water is a harbinger for doubt in the choices that you are making. You need to find another way to approach and solve your problems. Do not judge people according to their appearance. This dream is unfortunately your refusal to acknowledge some conflict or inner turmoil. Someone in your life undermining or working against you.
Drinking oil water dream states overwhelming anger or evil. You may be lacking spiritual enrichment and sensual expression. There is an emotional situation or problem that you can no longer avoid. This dream is unfortunately a warning for being consumed by your own ambition or obsession. Instead of confronting a situation, you are dealing with it by burying it and trying to forget about it.
If you dreamt about drinking oil water:
You would do best not to take offense at something your partner (current or prospective) may inadvertently say to you today, even if you do feel hurt. There is a chance that it could escalate out of all proportion to the original problem and become more than a simple disagreement. If you truly love each other, then just let it go, and no harm will be done.
