lol, I use to trip at my parents house when I was around 14-17. It wasn't easy to keep it a secret at times. Actually had my dad walk into the room and start talking to me once, when my mind was out floating in the endless abyss of the multiverse. I was too far gone at the time to understand anything that he was saying, so I just smiled and nodded until he left. He was drunk at the time so he didn't even notice that I wasn't fully present mentally, but it would have been really bad if he had freaked out on me while I was tripping that hard.
Anyone else here ever feel like their Veins get larger, more pronounced through the skin, and start pulsating rapidly larger to smaller (so fast that you can see it happen), while feeling like they have Neon Blue Electricity waves running through them. Happens to me every time I trip on Blotter or Geltabs. Tis a really strange feeling, and kind of freaks me out if I pay too much attention to it.
