What Caused the Shift in Your Trips?

It seems as if your earlier trips were mostly harmless, sometimes downright enjoyable. And as you grew older, you started to travel to more upsetting places. Do you think there was a reason for the change? I don't know. Growing up is part of human life in the same way that your ability is a part of you. They should have worked in harmony. It seems more likely to me that the shift would have been caused by a shock to your system.
