If people's mannerism influence who you are, then what is going to happen to when you are in deep in hyperspace?

There are entities there that will show you things. Things that will provoke an emotional response. I am not trying to scare you, but warn you. If you aren't in control of your emotions & mind, they will feed off of the chaotic emotions that they caused and become even more powerful.

IMHO, I think you should make sure your are 110% emotionally & mentally stable before you jump into a world where the slightest thought can send you spiraling out of control.

Peace!
