Have you heard about Sensory Deprivation Tank?https://www.healthline.com/health/sensory-deprivation-tank#TOC_TITLE_HDR_2 I tried it during my first trimester of pregnancy and it was super interesting. I confess I freaked out in the beginning but then I had to find my center somehow and when I did, I relaxed. I was skeptical I would last for one hour but when I heard the bell ring, I was surprised the time has passed that quick. I recommend it as an alternative therapy for different mental issues but also as a personal development aid.
