Help please..

I’m 41 weeks, due at any point now. At 36 weeks pregnant I experienced the only way I can describe it is ‘out of body’ experience. It was so scary, I’ve never suffered with anything like this in my life. I have been googling and this like ‘deperilisation’ have come up and I’ve been reading people’s experiences and they’ve said they’ve had it everyday for the rest of their lives… I’m so frightened. I wish I never googled the symptom I had, I’m thinking all sorts is wrong and now I’m thinking I have deperilisation or dissociating and it’s frightening me. I have spoke to midwife about it. Any advice?
