Hi! There have been many topics about this, and if you are really bothered you can look here at the BIG OBE topic.
Asking that question about OBE’s usually yields the same question as about HH. It’s as scary as you think it will be. A lot of people get excited or scared with the disconnect of their body, and end up snapping back. It is always best to remain calm and not expect anything bad to happen. I do not believe they are dangerous, though they can trick your mind into thinking they are. Again, just remain calm and remember you are in control.
