It is brainstorm BUT if you also think green storm or brain needle it can sound like those too. Seeing the words entrains your mind to one or the other. Try thinking those other two. The words fall into a similar pattern of the wave the word makes. Come to think of it, maybe some dogs hear "yanny" instead of squirell.I really don’t have a clue how it can be that when i focus on brainstorm that i hear brainstorm and when i think on green needle that i hear that.
Can anyone explane it to me?
