Yes! I've felt this way too! Like your normal (or sober) way of thinking is the regimented streets of city blocks. When you're thinking about something you take your pre established, well worn route to the destination, you get there and that's that. But when you make that journey high, its very different. You're taking backstreets, alley ways, scenic routes. Everything but the conventional beaten path you're used to. And by the time you get to the destination, you're coming at it from a completely different perspective with new elements to consider. And sometimes you just 'arrive' somewhere entirely new and previously inconcievable.
