Accidental Projections

TLDR SYNOPSIS: IS IT POSSIBLE TO ASTRO PROJECT ACCIDENTLY DURING DEEP DEEP SLEEP?

Hello all, I was wondering if Astro projections are possible during deep deep sleep. I ask this because my partner swears that he only feels an unknown/ghostly/paranormal presence when I'm asleep. He always hears people walking around the house or gets the cold spots/goosebumps feelings when I'm zonked out cold. I am someone who totally believes in the paranormal, being by experience growing up in an extremely old house that was haunted. I never feel anything paranormal whatsoever in my house. My partner made the correlation of only experiencing paranormal stuff last night when I was dead asleep in bed while he was up on the couch. He heard someone coming down the stairs, and as it frightened him and made all his hairs stand up, he thought it sounded like me walking. As he is someone who is very open minded and spirited, he thinks that since I'm so free spirited and being someone "trapped" in this physical world, that I let my soul leave my body while I sleep. Was just wondering if this is possible, as since he brought this up to me, I can recall times that I have done this but just thought I was dreaming. Thanks everyone!
