Accepted Answer

[rɪ'kɜːr] 
recurhappen or occur again
Have you ever had the same crazy dream night after night? If so, you know that dreams can recur, meaning they repeat, or happen again.
The verb recur is used to describe something that happens over and over, whether it’s an injury, an argument, or a character who pops up from time to time on a television show. Recur often describes an event that happens repeatedly, but it can also be used to describe something, such as an image or a memory, that for some reason just keeps popping back up in your mind, like self-doubt that recurs every time you worry about something.
