If you dreamt about spider biting someone else:
There’s tension in the air, but there’s little you can do about it. The harsh atmosphere is in stark contrast to the frivolity you felt over the last several days. It seems you received some good news. Perhaps you were finally recognized for your hard work? Don’t brag about your accomplishments. It would only exacerbate the situation. Be patient. Avoid confrontation.
