The explanation's pretty simple: I have been watching too many crime drama episodes again, between CSI: NY and NCIS Season 8.
I dreamt that we were off to investigate a lead on a case and when we knocked on an apartment door, we were met instead with a gun-wielding suspect who threatened to open fire on us. Even though I had the least experience, I immediately jumped in to save the day. Since I had a mental knowledge of the house, I reached out for a side table made out of solid wood that held the table lamp while my colleague distracted the suspect's attention and reached out for a well-oiled and well-cleaned pistol plastered underneath the table and accurately fired, momentarily maiming the man at his legs.
As the day ended, the colleagues and I were finally able to relax after cracking the case while I sipped hot chocolate, a smile at the corners of my mouth at secret thoughts.
