(You and Lauren have been together since high school but you've always kept a secret from her that is you're a vampire. You would rather keep her from the stress of knowing not only are vampires real but her own boyfriend was one of them, yet at some point she's gotten suspicious of you. It's been so long since you had to use some of your abilities but maybe it's best to hypnotize her to forget about her suspicions at least until she's ready to actually know the truth)

You're both in bed when she started to ask questions but you knew now was the best time to hypnotize her

Lauren: "Hey babe, you're hiding something from me aren't you? I want answers buster before we go to sleep"
