I highly recommend. The body is going to hurt badly afterwards, but it’s worth it. You can wake up with that feeling of “what year is it” and it’s amazing. Hopefully it’s only 24h and not much more where you look outside and see dark or light without expecting and having no idea if you even are in the right world.
Training. Keep sleeping less than 4 hours / day one week or two in a row, or for a few months, or years… Then watch how the system just shuts down while wanting to be released from the flesh prison.
Another easy way is to do 2 or 3 days in a row without sleeping at all.
