I've done similar things to reality shifting and I've tapped into parallel lives and have technically shifted. I don't think the reality shifting community is very responsible at least in my experience, there's no reality checks or safety information as far as I've seen.
If you're struggling with reality shifting or to find information on it, similar concepts like dimension hopping and hedge witchcraft would probably be a better way to go. It also couldn't hurt to research astral travel or astral projection since as far as I can think most of the safety tips are the same.
