A TIKTOK "time traveller" has shared a new video in which he tells of his fear of being trapped alone in an abandoned city in the future.

       Javier, who bizarrely claims he was posting from the year 2027, has previously filmed deserted streets in Spain lined with cars and buildings and now has uploaded a clip which appears to be inside a secret passageway.

       In the video he can be seen walking down a flight of concrete stairs to a passage which resembles a nuclear bunker.

       A caption reads: "I’m tired already. I no longer know what to do or where to look

       "I think I'll have to get used to being here alone forever."

       After walking through reinforced concrete corridors which are lit with bulbs he reaches some stairs which appear to be blocked off by a glass panel.

       In a previous clip he is filmed walking past flats and a children's playground with no one in sight.

       Another eerie clip appears to be filmed with a drone and shows him standing alone on a beach.

       Javier shared the strange videos with his 6.4million followers on TikTok this week.

       It follows similar clips showing deserted shopping centres and supermarkets in Valencia.

       Javier, who goes by the name @unicosobreviviente (only survivor), posted his first video on February 13, claiming the city was deserted.

       Javier captioned it: "I just woke up in a hospital and I don't know what might have happened.

       Some users have asked how come there is still electricity to power lights and escalators, and internet to post his videos on TikTok.

       He replied that he wasn't sure but "most likely there is a type of connection between 2021 and 2027".

       Javier also shares updates of his "life in the future" and claims he is "stuck" and is trying to find a way to come back to 2021.
