Ive read that while they're all disassociatives, DXM is still a pretty different experience from ketamine. I personally havent tried the latter though, so this just secondhand information.
It is similar, but you won't go down like with ketamine. So while you are in fantasy land, you can walk, talk and interact.
It is a fun drug to do in nature far away from the city, talk to elves, clouds and trees. Just lie down, think about silly things and watch the clouds go by, it is very peaceful, almost child like. That is the good side of pcp.
In cities I can imagine it is hellish, but perhaps also adventurous if it is an quite old city with dark alleys. I never dared to do it in cities.
And when you are back, you know it was just fantasy. It is like walking into a book of Neil Gaiman. It stimulates the fantasy and makes you more open to whatever comes up. It lowers your shields of critical thinking. (And that is where the danger lies too btw, so keep notice of that)
In a hectic city that goes wrong, but in a nice safe place in nature. Even if you meet a stranger and have a talk with him, he tells you his story and you marvel in it, it is fine, it is very friendly. Almost magical.
It can be fun, but it can also bite you seriously. Be safe and watch out :) It is not as safe as ketamine and not as safe as LSD. Too much makes you look like some futuristic drunk, so you really need the get the dosage right. It is on par with alcohol (society's favourite NMDA antagonist) with the stupid things you can do on it. Only alcohol puts you down at a certain moment, so it limits the damage. PCP does not, well not enough.
