I've had a couple recently too. One I was on a train trying to shoot dope (which I've never done in real life) but couldn't get a vein. Felt like I was sitting on that train for a couple hours trying. I was very glad when I woke up.
Another one I actually snorted some blues (30mg oxycodone). I woke up and felt like I had withdrawals all day.
Hope you're doing good and staying strong, peanut.
