This part 2 dlc was actually pretty fun imo. My favorite part was Friedlander's entrance speech because it felt so action-movie like. Our GTA online character taking out the 2 guards in the dark was awesome. (Also our characters flying into the back of a plane like trevor in minor turbulance was a neat scene.)
It's an actual thing. Look up "tripping, ego death". They just made it silly in this, but it's something that happens when you trip hard enough, especially from DMT.
To be specific, it's when you lose all grasp of who you are and what you are. You "lose" yourself (or die) and end up feeling much more in tune with the vibrations of the world around us.
At the end, I should have saved the outfit as the bikini. Actually, you can get a bikini top and bottom at Suburban and save it as an outfit. I replayed the last mission and she ends up back at the freak shop. Then I went to Suburban and realized I could put her back in the bikini and save it. Looks weird without cloths on. I like her in jeans and the sand rolled t-shirt.
