I'm I greening?

I know greening out is different for everyone but I don't know enough people to know if that's what I'm feeling. I've smoked for about a year so I know how much weed gets me to certain highs, but recently I've gotten to a high where anytime I get to that high something goes wrong like last night I felt something was wrong inside of me and freaked out thinking something was wrong and I feel more susceptible to freaking out. So my question is am I starting to green out or is that just a weird high?
