Tripping [trip-ing]

tripping [trip-ing]: verb

A state of mind brought on by experiencing a different state of consciousness - mostly through vast changes in perception, senses and thought patterns.

Example: When I was younger, the world seemed a more vibrant place. It was much easier to daydream or lose myself in my thoughts, or imagine things as though they were real. Music felt really alive, as though it connected with me somehow, and I could spend hours following every crevice in the pavement on the way home from school... where now I couldn't care less. That is how I viewed the world as a child... but having matured since then those abilities have been lost as a result. Tripping makes you more aware of all the details that pass us by- and whether it's through drugs or natural causes, tripping is a great way to realize all the finer things around us that we normally take for granted.
