I’ve heard that the elastic can wrap around your neck during the ascent after the first bounce. Is this true?

Colliding with the bungee in the “zero gravity” moment, which occurs after the ascent phase from the first bounce, is rare but not to be excluded. We always recommend not touching the bungee ropes during the launch. Any other situation is completely fortuitous and has never occurred in over thirty years of activity of our Bungee Center.
