Yes, to a large extent. The horror genre trends in real life were a big part of what inspired 'Scream'. For example, the over - the - top nature of some horror movies and the common tropes. The movie also seems to be based on the general idea of how real - life killers operate. They often target victims in a somewhat methodical way, and this is reflected in the movie. Also, the public's reaction to real - life crimes, like the hysteria and the need for safety, is also shown in 'Scream'.
The true - story events that influenced 'Scream' include the concept of a community in shock due to a series of murders. In real - life, there have been cases where a small town or neighborhood has been terrorized by a killer. The movie also takes inspiration from the way victims in real - life cases often have some sort of connection to the killer, whether it's a past acquaintance or something more subtle. In 'Scream', the characters are often targeted for reasons related to their relationships or actions, similar to real - life criminal motives.
Yes, 'Scream' is loosely based on true stories. It draws inspiration from real - life serial killers and horror events, which gives the movie a sense of realism and makes it even scarier.
