Ive had feelings like that alot lately. I cant explain it either. Its very scary. Try to do things that are safe and remind you of whats real, and try talking to some friends about things on your mind. I know its hard in the crazy lives we live. I find myself feeling like a work zombie so often these days it has me tripping about whats real and whats not. I hope you can find peace. Best of luck to you! I know its scary.
The light headedness or numbness could be caused by anxiety which can cause mild hyperventilation that could make you feel dizzy numb or zoned out. I believe you should talk to a dr about your symptoms. No need going in and in. It feeling we’ll orcas if something is not quite right.
this might be because my life has consisted of playing games eating and sleeping for the past year and for instance when im riding my bike on the occasion i do go out it feels like i zone out then realise im riding a bike thats what i mean by my body and mind feel separated
