For the past 2 months whenever I would realize I was dreaming, I would feel a heavy pressure, or see some strange bright lights and wake up. Last night I realized I was dreaming but immediatley after I realized that, I felt this REALLY heavy pressure on me, it was like I had a boulder on top of me, and I faintly heard this voice that said something like, "No! This is reality!" and then I woke up. I don't know why this is happening, it's like my mind doesn't want me to become lucid. This didn't use to happen before.
