The first thing you do when you realize you are all alone is to try and use your mobile phone to call for help.
The plane was in complete darkness when Tiffani woke up.
Upon waking up, she found herself all alone on a dark empty plane, freezing cold and with no means to contact anyone.
She said airline representatives apologised and said the carrier would investigate. This is exactly what Tiffani did only to discover that her battery was almost dead and that there was no way to charge it, as the aircraft's power was turned off.
"I think I'm having a bad dream", she recounted in the post.
"I'm trying to focus on my breathing and control my panic attack while I attempt to charge my phone by plugging into every USB port I could find-no luck because when they shut the aircraft down there is no power whatsoever", she wrote.
"I'm full on panicking [because] I want off this nightmare ASAP".

A hard match was lined up for them against India on Thursday at Trent Bridge but the match was abandoned due to rain. In the match reduced to 43 overs per side, New Zealand beat the Proteas by 4 wickets with one ball remaining.
Ms Adams found a torch in the plane's cockpit and found her way to the main door. Facing a steep drop to the tarmac, she leaned out of the aircraft and called over a ground crew, who got her out.
With flights though, there is no such risk, as you know that if you drift off to the land of nod, a member of the crew will make sure you get off the plane once you've landed.
"He tried exiting out of the front door, and we stopped him, so we went to his seat and we turned on the lights bright".
Eventually she flagged a man driving a luggage cart who happened to be driving past the plane. She said she used the flashlight to illuminate the door and managed to unlatch it, but after opening it she looked down and noticed that she was suspended dozens of feet in the air.
Air Canada have since called Adams twice to apologize and say they're now conducting an investigation to determine how the plane's crew managed to miss her before disembarking the aircraft.
"He [asked] how the heck they left me on the plane", Adams wrote, adding, "I'm wondering the same".
Adams also claimed that after she made it home, Air Canada was in contact with her the following days to apologize for the inconvenience and that they looking into the issue.
"I haven't got much sleep since the reoccurring night terrors and waking up anxious and afraid I'm alone locked up someplace dark", she wrote.
