The main difference is that ketamine and most other dissociatives physically inhibit people. You couldn't fight your way out of a paper bag in a k-hole, but on pcp you aren't subdued in the same way and can get yourself in trouble with the feeling that you can do anything.
LOL at the paper bag thing, so true.
Same goes for me with MXE. I take a large dose and I can hardly move.
On smaller doses of MXE, and more so on 3-MeO-PCP, I have felt great surges of energy and have been able to move fluidly and with good coordination. I also found that I could lift things (with one arm) without effort which normally I would huff and puff over. It's amazing the power of the mind. Once in that rare state of enhanced strength, I was doing some gardening and saw that I needed to empty a heavy bag of garden soil into a wheelbarrow. Usually I pick those up with both hands and hold them close to my body to keep my balance. On this occasion I felt strong and I had no doubt that I could lift it, and - voila - it flew up like it weighed 3 kilograms instead of 15. I held it in one hand with my arm fully extended away from my body. I felt no strain at all and was no sore the following day.
I've since tried to repeat the experiment (both in a substance-free state and also on dissociatives) and never been able to repeat it. I put it down to the mental state I was in at the time - the fact that I simply had no doubt whatsoever in my ability to lift the bag meant that it happened effortlessly. Now if only I could harness that mind-state and have it available whenever I needed it... there'd be bags of soil flying all over the place.
I felt like I had incredibly strength and could take on anyone and preceded to punch a pillow..
I LOL'd at this, too. It's quite nice, really. It's great to feel that surge of energy and if you have the impulse to hit something, why not hit an inanimate object (especially a soft one)? I think it's cool when people can experience these feelings of power and strength with self-awareness and a degree of objectification, not becoming identified with it or feeling the need to use it against someone else.
It's a pity that young people in my city who like to drink lots of alcohol and/or smoke meth and then look for someone to beat on don't explore their impulses in this detached and self-aware kind of way.
