Shock after meditation?

I was meditating daily but I was not able to meditate for long but today I meditated very deeply for an hour. It was blissful, thoughts for so less that I couldn’t remember them at all I just forgot them. I would ve meditated more but there was a big explosion near my house I and I opened my house with something like electric shock not painful but shocking shock it just burst through me. Can anyone tell me what is it? Is it common?

normal human reaction. getting jarred of sudden interruption when in a different state. happens all the time. Similar to when your trying to sleep getting close to getting knock out and then you get sudden loud noises.
Same thing when your in hypnosis and suddenly get out of trance too soon. it’s called hypnotic hang over. Easy fix is to get back into trance and slowly come back.
