Mind Reading
Although it is impossible for humans to actually read the thoughts of others, they are capable of inferring their feelings and thoughts through the use of mental models. This is referred to as empathic accuracy, and it entails "reading" signs that are expressed through another person's words, feelings, and body language. Most people can read other people to some extent, however persons with psychotic disorders or autism spectrum disorders may find it difficult to understand other people's emotions or social signs.
Finding electrical and neurological signals in the brain is one thing; reading and capturing what is happening inside our thoughts as we perceive it is quite another. Many of the machines in your neighbourhood hospital could accomplish the first goal. The latter, however, is a barrier that we never believed machines could overcome, since awareness consists of much more than just electrical signals moving through the brain.
It turns out that it's not, after all. We now have computers that can recognize a song playing in your head thanks to artificial intelligence (AI), as they learn the relationships between brain signals and particular musical cues through machine learning. even if less accurately than the tunes, you could try to replicate the picture you're picturing (though still high enough to be creepy).
