Give more detail. You said you had a couple lucid dreams but since have had some odd experiences in waking life and dreaming. But what techniques are you using? Has anything changed in your life? Routine? Emotional state?

Honestly, I might not have an answer. But for you, I suggest zooming out and looking at the big picture and what has changed in your behavior. It may simply be that you need to be more diligent with your technique. It's typical to experience some weird dream or hypagogic experiences. It's also typical that lucid dreams are irregular and seemingly random at the beginning, despite a consistent effort. Keep at it.
