same problem I had, all dressed up for the party and no place to go!
you need a deep seated intention to travel, just being able to be obe is not enough.
that's why studying phasing or doing retrievals is easier, because the intention is to assist someone.
but we do go obe and don't remember it as well, or just snippets of it.
like Bruce was told he was at the library all the time but it wasn't until later in his development that he was told this by a guide. he had this long involved conversation with a librarian that he was always there.
I'd say just be specific, name a specific person and state your intention for visiting strongly enough to impress yourself. doing it this way may take a week or so to manifest an experience but it works. yet with phasing you just let yourself go through an imaginary door. you don't really need to have your astral body with you to get verification or info.
or even a retrieval. same with the hall of records, have something specific you're looking for in the records. the more you think about it, the more it tends to cement your request. good luck!
I never heard of the 45 degree angle lift out, but I have heard of pulling on a string to get obe.
