It can be absolutely wonderful if you're properly prepared though, just lying in your bed with a dim pink light on listening to Carbon Based Lifeforms or something, enjoying escaping your body for a while and floating around in an undefinable sea of warm nothingness.

However, it absolutely sounds like it could be hell if you're not prepared though - especially in police custody, but even just fighting against it in a party situation where you want to exist and be social could be problematic.
