not many risks at all just make sure not to do it too much in one night bc technically you arent in deep sleep when your out of your body and sleep is still very important
watch out for vampires that can be any entity that feeds on your astral body and dont piss off any strong entity or they will attack you when you enter a state they can affect you. however its highly unlikely you will ever come across powerful ones like that.
just learn to banish enemies using your own will and youll be fine just in case someone powerful comes along but to be fair ap is alot more safe than the real world haha
It can take a long time and a lot of self discipline to get good at it so be patient with yourself. Try and set a time schedule for training and practiceand stick to it.As far as risks go I would say you get out what you take in with you. Check outRobert Monroe Institute youtube channel, they have some good information on AP.
Possession is a possibility since you're basically leaving your body empty. This in my perspective creates a void that some spiritual entities will find as an opportunity to take over. Keep up strong protection chants and spells around yourself before performing astral projection, and read up on multiple banishing spells.
There is a lot of fearmongering Regarding astral projection. You cannot get lost. You cannot be possessed. If anything goes wrong, the worst that happens is that you snap back to consciousness. If anything bothers you, you have the ability to leave it or to tell it to leave you.
