Was I close?

Never had a super o but I think I just got close, Im very new to this or 4 or 5 sessions. I was using my aneros trident and about 10 min in I started involuntary shaking, about 10 min after I realized I wasn’t controling the massager anymore. Then I physically felt my heart pound and my face and chest felt really warm… Then I immediately came out of it and couldn’t get that feeling again. Kind of discouraged I think I was overthinking it in the moment but I’m not sure,

advice would be very appreciated
