No. You can sense future events to come, usually near future and when it happens it is surprisingly vivid and accurate. We have very complex brains, capable of precognition. Essentially, in the same way your visual cortex calculates a yellow color probability ( we don’t SEE yellow, we calculate it) on an object, it is also capable calculating probability of events, even when those are very specific. This skill enhances when we socialize with people who also can do this, because we start mimic each other ( they still don’t know HOW we do this) like a flock of pigeons, and with time because of neuro-plasticity our brain accepts those patterns as its own. You are not going crazy. But, check if your recent social environment changed and includes a person or people who can do the same, in case you did not experience anything similar before. It can also be a result of lifestyle change or maturing of a neural cortex ( some things like this irational chaos prediction skill come later in life).

One time I was going through a break up. And even though he said he wasn’t seeing anyone else. It flashed thru my head that he was lying and I knew who it was. Ended up being true and ppl were asking how the fuck I knew when they didn’t tell anyone
