I have many years of experience with astral travelling as a mental exercise only. I do not time travel using the technique.
I have read about black box psychic devices such as the HDR device. To me, it is plausible that you can experience many things mentally only -- but not physically. I have not bought an HDR device or tried any black box type device.
