As your mom told you don't do anything bad that looks good or anything good that looks bad. It normally ends up biting you in the ass. Also, don't do anything that would jeopardize any of your work relationships. You know what you did and look a year later it came back to haunt you not from the direct party involved but a close relation that could have really fucked you.
Really it could all be a hallucination but there is enough guilt there for you to question the whole scenario.
