Ah, transcendant meditation then. Be careful with that. Your soul is actually projected and can be ensnared if your cord is severed. It's a safer bet to ratchet it down a few notches to a milder form were you are only a distant observer.
During your visit did you communicate with any entities there? If so what did they have to say?
Most of the times i've been there I was just 'observing'. I've communicated with entities both human, elementals, angelic and demonic beings.
Most humans you speak to in the inferior worlds don't even know where they are or that they are dead. The ones that are aware are black magicians/sorcerers and it's best not to interact to much with those types. To give a vague favlour of what hell is like it's very similar to the film silent hill where you have all the people in perpeptual darkness living in ruined cities and they aren't aware that they have died.
It's very complex as you dealing with different spheres all over-lapping each other. Initialy hell can seem quite alluring there's drugs, bars, sex and all other forms of vice but it sucks you in then imprisions you and things very quickly become 'hellish' and not nice. Kind of hard to explain until you see it for yourself. The story in Pinochia where the children goto a playground and indulge in lots of pleasures but then turn into donkeys is a good allergory.
The superior worlds (heaven) is a totaly different matter. It is truly amazing, happiness and freedom beyond your wildist dreams. Beuatiful architecture nothing ages or deacys. Even the grass grows in geometricaly beatiful patterns. There is no fear, anger, war, poverty, class or divsion.
The problem is getting into the superior worlds is very hard because you have to be purged of all sin and desire. One of the reasons heaven remains the way it is because 'sinful' people aren't let in there. If you seriously working spiritualy though you will be allowed visits there to motivate you to keep working and eliminating all your vices and lusts.
