Everything was normal and the night was still young when three guys I knew came over. Soon after I was told they had insufflated a small amount of special K. Although, the preferred way to take this drug is by intermuscular injection, because it takes less and produces a stronger high. They said, they only took a tiny amount compared to cocaine, and it kept them high for about a hour.
They acted normal as far as I could tell while sitting outside on my porch without a light on at night. Their motor functions weren't impaired, but you could tell they weren't quite all there. Their moods and personalities were different, and I had to ask a question several times before it would sink in and have one of them answer it. They were infatuated with their own ideas. They were in their own world with limited contact to the outside. In a hole, you could say. While in the hole some say they experienced alien like visions of their lives and conversations with god like figures. These hallucinations in the medical world are called emergence reactions, and would be more like DXM and PCP, and not shrooms or LSD.
After having to ask what it's like a couple times, I was fielding answers from all three of them.
"You get lost in your pocket", described one friend as another tried to explain to me the k-hole.
The other two agreed, it's like getting lost in your pocket. One of them told me about how he lost his cell phone. The phone was still in his pocket, but when he stuck his hands in his pockets and couldn't find the phone. His words came out slow and stilted, talking was hard but not impossible. Then the other guy said he felt like he was actually lost in his pocket. This for them I guess described the disassociated feeling that comes with ketamine.
Soon the conversation was on three different topics again, and I felt like a untrained border collie trying to herd a flock of sheep back to the pen. In this case the kitty kiddies back to the conversation's original topic. It seems that the feeling induced by this drug is so simple it never takes someone long to describe it thoroughly.
Imagine the k-hole as feeling confused constantly, and the ability to be dumbfounded by those things stupid. Time stands still, and your movements seemed delayed and controled from a remote outside source. The cause and effect of problems are easily recognized, and the emotional connection to spoken words are more intense. The experience is pleasurable, but isn't very rememberable which is typically expected with higher doses.
Experiences may vary due to weight and mental state.
This is only my personal experience viewing k-hole's inhabitants, but some highly suggested reading can be found at;
