When you escape the prison planet, it looks like you are still going to need money in the astral world/other dimensions. Here's what an interdimensional insectoid entity told a man, is used for currency in the astral dimensions.

In the book Far Journeys by Robert Monroe, he traveled to an astral city inhabited by human looking beings but was told by the city's security agents that he couldn't enter private spaces without paying first. Many other people who have OBEs have said that there are huge cities in the astral dimensions, some of them inhabited by the souls/spirits of deceased humans. I've often wondered if the functioning of these astral societies necessitates the use of some form of currency as a way to store & trade value. Are there banks in these astral worlds? Stock markets? Bond markets?

But if astral beings can manifest anything they desire by simply thinking about it, why would they need money? And if money existed, couldn't it be easily counterfeited through thought manifestation? So, in the astral world, if there is a need for money, the money would likely follow similar rules to money in the physical world. It would have to be something that's difficult to acquire, each piece would have to be unique, couldn't be duplicated, couldn't be counterfeited, etc. So what could be used for money? Well, see below....

Another Experience with Aliens From the article "Aliens, Insects and Elves! Oh, My!" by Jon Hanna

"About a decade later, I was camping with three friends at Island Lake near Nevada City, California. A couple of us decided to take "heroic" doses of Psilocybe mushrooms one evening. I chewed down four grams, retired to my tent, closed my eyes, and got horizontal on my air mattress. As the effects of the 'shrooms came on, my inner vision revealed what looked like a dank moss-green hospital emergency waiting room. I seemed to be sitting on a bench in this room, and it occurred to me that it was odd that there were no patients being wheeled in or out. Kinda quiet for an ER. After some time, I noticed a few off-white football-sized larvae floating three or four feet off the ground in various spots. Following one of these with my eyes, I then saw an insectoid entity about the size of a small dog, whose back was facing me. It had a long mosquito-like proboscis that I could only partially see. Suddenly, it turned, and--realizing that I saw it--it made a high-pitched buzzing/shrieking sound. (I got the impression that it was sending out a warning alarm.) The entity then initiated telepathic communication with me, explaining that it was quite surprised that I could see it, as this usually didn't occur. It said that it lived by extracting human thought/emotion. Human thoughts were both the currency of its species, as well as their sustenance/energy source. (The needle-like proboscis was looking less friendly by the minute.) I was given the impression that--as the coin of its kind--different types of thought/emotion were valued differently; those with a more intense energy charge, such as fear or love, were worth more. The entity explained that it existed in another dimension so that it could feed off of human thought unhindered. (I got a feeling that the relationship wasn't symbiotic; perhaps these "thought drainers" somehow suck life energy from humans, along with the mental energy.)
