Technology has greatly developed that so many ways of communication has been created. But in the future, there will be more means of communication in the future. One of that is telepathy. According to Cambridge Dictionary, the ability to know what is in someone else's mind, or to communicate with someone mentally, without using words or other physical signal. Telepathy may help people communicate in situations where verbal or written communication is not possible or desirable. For example, telepathy could be used to express what's in your heart or soul to others who have a close connection with you, or to deliver messages that can't always be realistic in face-to-face conversations. Some people believe that telepathy can also help them connect with other beings, such as animals, plants, or even the stars. The most important benefit of telepathy is that it offers the opportunity to more easily exchange large amounts of information than our present methods of communication allow. But telepathy has many disadvantages. It could violate their privacy and expose their secrets, feelings, or intentions. This could lead to embarrassment, blackmail, manipulation, or betrayal. Some people may prefer face-to-face communication over telepathy, as it allows for more non-verbal cues, such as body language, facial expressions, or tone of voice. If telepathy is not well-developed or regulated, it could cause unwanted or harmful effects, such as headaches, noise, intrusive thoughts, or mental overload. It could also expose people to negative or harmful influences from others, such as lies, threats, or curses.
