I'm new as well, though welcome to Spells Of Magic. Hopefully we find what we have come for. As for hypnosis I unfortunately do not have any knowledge of it nor experience, besides being under hypnosis once for a college event. Anywho, I suggest researching the topic and make sure you cross reference your information. I also suggest, unless you already have, seek professional help for progression in working out past traumatic experiences. I speak from personal experience in regarding therapy.
Now for magical purpose I suggest as stated earlier to research the subject and cross reference your findings. I do not recommend Wikipedia, but if you decide to go thay route follow the citations of the subject. If they're not present, cross reference.
I hope this helps.
