I wouldn't know what to tell someone about what entering a (the?) void is like, but the closest i can imagine is a situation where you're 1000 nautical miles out to sea in a small sailboat on a pitch dark cloudy moonless night, far away from anyone. A storm is brewing and the seas are getting large, though you can't see them, it's too dark for your eyes, though you feel the force as it throws your small boat around. It's more than you bargained for, but there isn't anything you can do about it. You're in it now. You're losing control of the boat. You're afraid of what will happen if you lose control, the seas grow larger... The rains and the lightning and thunder are here and it's just too much too bear, so you go down below and lay ahull, surrendering to the sea and forces beyond your control. The sea will make of you what it will, you're fate rests with something larger than yourself. A part of you dies that night, and what emerges the next day is different from what was swallowed by the storm. Your old self at the helm, somewhat unrecognizable. And a part of you never made it out of the storm, remembering that you're always out to sea, and that you needed to come out here to remember that.
