AMA about deliriants! Experiences, pharmacology, etc!

I'm planning on taking DPH as my very last hallucinogen in my journey with these substances and I have a few questions:

1.) What is your recommended dosage for someone who wants to try it once and experience its effects as safely as possible? And should I factor in body weight to said dosage?
2.) Any advice for my sitter and what they should do (or not do) to help me through my experience?

3.)Will being mentally prepared, or in the right mental headspace with full knowledge of what you're getting into help?

4.) In my research I've read that THC can have an inhibitor effect on the experience, is there any credence to this to potentially "bail out" if the experience is too much to handle?

5.) Do you have any experience with attempting to use this to "enhance" or influence creativity in the arts?

6.) Is there a possibility that this can be be a tool for overcoming arachnophobia?

I'm still doing research on this drug and I'm trying to approach it as responsibly as I possibly can (as much as you can be with something like this) so any additional feedback will be much appreciated.
