Talk to General Practitioner on Feels Like Something Goes Or Enters Inside My Nose And Went In My Head

As I was sleeping last night , I felt some sensation in my nostril and I think I mistakenly (as I was in my sleep and unconscious) I inhale and take a long breath as normally we all do in sleep and then I felt some unusual feeling. I instantly started exhaling out the air through my nostrils to make the thing goes away or comes out from the pressure if anything tried to entered. But since then I'm unable to sleep again and went bathroom few times and trying to sleep again but unable. Whenever I lay down on bed to get sleep, few moments later I started some strange feeling in my head and vision or dreams looks blur.

Is it serious or need a check up or consultation ? as I feel something goes or reached to my head which is disturbing me and can cause some serious issue.

Please guide and advise.

Thanks
