You know how if you go to bed thinking of scary things you can have a nightmare much easier? If you go into SP with that mindset you will likely have bad hallucinations. Just go into SP not really caring, or with a good mindset, and it won't bother you nearly as much... I went into a WILD a while ago thinking about some of the scary hallucinations people see, and, of course, I heard and saw some things I didn't want to see. You can still see some pretty freaky things even with a good mindset though but just ignore it and it won't be as bad.
