Vivid dreams? 😳

So I keep having extremely clear and concise dreams that feel totally real and last a lot longer than I knew they could before. Most of the time they're just random and weird, but sometimes they're nightmares that wake me up nearly gasping for air at 6 or 7 in the morning. 😕 Does anyone else experience this as a pregnancy symptom?? And what's the craziest dream you've had? 😂
