Hi jc84corvette,
There are certainly a lot of members here that can give you input on your questions. They are excellent fundamental questions too. Take a look though at the following website where you will be able to read a Treatise on OBE written by Robert Bruce. Mr. Bruce also wrote the book Astral Dynamics. If you are able to buy a copy of the book, that will answer a lot of questions also. Meanwhile, here's a link to Robert Bruce's website and his treatise:

Additionally, if you use the search engine feature of this forum, you can type in "good obe books" for example, and most likely discover some other recommendations.
Regarding your questions, I'm not avoiding them, I just can't give you the benefit of personal experience as I do something a little different called astral phasing. However, someone may come along who has had experience with OBE's and give you some direct answers.
Finally, you can also use the same search engine (located above) to help you find previous posts related to the OBE experiences you ask about.
Very best,
Thank you, and please, those that can answer my question, please do it. :)
