My remote team meeting had a topic that vanished from everyone's memory

We had a video call yesterday to go over quarterly goals, and I clearly heard our manager mention layoffs as a possibility. When I brought it up in chat after, two teammates said they never heard that part, and the manager denied saying it. Now I have notes about layoffs but no record in the meeting transcript. Did I imagine a whole chunk of the conversation, or is this some kind of office glitch?
