My fan theory for ride the cyclone
Ok so this is only a theory as I've not seen it confirmed anywhere but at the end of the show I think its basically Jane actually having died and meeting the group once more in the afterlife as at the start you understand they have died and you hear that song and at the end you can hear it so this must mean someone has died. Its also backed up by the fact they watch Jane grow old and become elderly so I think thats it .
(Also I feel like she remembered the entire experience and definitely can't wait to go meet her old friends again)
