Doctors, experts! Anyone! Please help! What wrong with me?

Out of no where sometimes when i think of something it feels like it was a dream orlike ive been there in my last life coz it feels like a playback or something. It goes for a few seconds and after that this funny warm feeling burns my heart and travels all the way to the left side of my body, to the neck, to my hands, tummy n legs, basically everywhere. Its this tingling feeling.. This lasts for around a few seconds to a minute.. Im not too sure because when it happens it feels like im in another world, im seeing other things that feels so familiar like ive seen it befire yet i dont know where it is and what it is or who it is and how i know them. Please do help me this is like the 5th time i got this and it comes and goes.. All i have to do is think of something and then that burning t hing happens again! After that happens, i forget what i thought about and what i see during the burning sensation. Please help i really dont know wht to do.. Is this a mini stroke? Or.. What? I dont even know the people that flash into my mind or most of the times i just dont remember. Anyone goes through this is well? Please help me.. I hate that feeling.. I feel so paralysed cz all i do is scrunch up and stay there motionless wawiting for it to pass..
