Gateway to the Supernatural

After assessing and studying all the primary data about the substance that I could procure, I was ready to try it on myself. The psychedelic substance known as dimethyltryptamine is the most illegal substance in the world. It is also known as the 'spirit molecule'; allegedly being able to open the senses of an individual to the realm of the supernatural.
Although I knew that the drug induces severe hallucinations, I was unsure of it's true capabilities; of what I would experience...of what I would see. But science is about risks is it not?

I prepared a dosage of 20 ml, which is considered average. I gazed at the syringe for a long time. The green liquid was slowly pervading inside the syringe. It was as if it the liquid moved on its own. It seemed to be alive. What was I saying? I haven't even injected myself and I'm already speaking nonsense.
Five, four, three, two, one...

I opened my eyes to see myself lying on the floor in the corner of my laboratory, facing the wall.
What happened? Did I faint? Why don't I remember anything that happened?
I glanced at my wristwatch and saw that it had only been twelve seconds since I injected myself. I could not understand what was happening.

I heard a half muffled voice behind me. Impossible! Nobody could have gotten into my laboratory; nobody knew about my laboratory!
 I heard the voice again; this time clearer. It sounded familiar.
The voice said my name. The person called out my name the way he used to when he was...with me.
A sudden paralyzing chill went through my body. Could it be? Impossible!

"Brian!" I yelled out in shock. I could not believe that my brother, who died two years ago was standing a few yards in front of me. He looked just as grumpy as he did when he was alive. His face had those little wrinkles and soggy colour that marked his early transition into the old age of forty. He was wearing loose white shorts and a loose white shirt. This looked unusual because Brian always wore leather jeans and a T-shirt. What was I saying, the whole thing looked unusual.
I wondered how the drug could create such a vivid hallucination of my late brother.

"Fascinating. The hallucination seems vivid"

He stood there in silence once more and then, he burst into laughter. The same loud annoying laughter usually heard years ago when Brian was alive. I sat there on the floor, perplexed by the hallucination's unjustified cachinnation.

"May, you're not hallucinating. This is real"

"Intriguing. The hallucination creates its own verbal persuasive response" I was more intrigued at how the hallucination called me 'May', which is the girly name my annoying elder brother used to call me.

"I'm serious. I'm really here. I can prove it to you"

I stood there staring at the hallucination while it approached me.

"It's amazing how the drug uses my brain- OUCH!"

The hallucination hit my knee with an iron rod! I was in pain when I realized that I was not supposed to feel the pain. Or was the pain another hallucination? No, it was too painful to be a hallucination. I tried to convince myself that the pain wasn't real...it didn't work.
I kept holding my knee while jumping up and down around the lab. Even as my imagination, my bother was still able to inflict pain upon me. He kept on laughing and pointing at me.

Finally the pain subsided. I was able to think straight again.

"I told you I'm real"

"But that cannot be. The laws don't allow-"

"May, the supernatural realm doesn't work on the scientific laws of the human realm" The man cut in.

"Supernatural? That is all mumbo jumbo!"

"What else do I have to do to make you believe? I could grab that electrocution device-"

"NO!" I yelled, not wanting to take any more chances. But then I thought, if it was not real, how could the hallucination have held the rod to hit me?

"All right May, since you don't want to believe, I'll make you believe even when the spirit molecule wears off"

"That is not possible"

"Hey, May, leave impossibility to be handled by me okay? Just beware that in trying to get you to believe, I will be making your life miserable. As your senses have been opened to the supernatural realm, the supernatural realm will  continue to be open to you"

As this was said, I began to feel dizzy. Everything abruptly became blurry and inconsistent. I lost consciousness afterwards.
I found myself lying on the floor again. I stood up and found everything in its rightful place. I took one stop forward and almost fell. My knee was wounded!
