You may find yourself reminded of the Bene Gesserit litany against fear from the novel Dune:"I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I will remain."

Even though these are just words from a science fiction epic, they contain a great deal of truth. Assuming you've followed the guidelines of safety recommended in this FAQ and you are with people you trust, suspension is relatively safe and you really don't have anything to fear. Whatever fear comes to you, relax, accept it, and let it pass by.
