are these allergy symptoms?

[Abel Skivver]

because it seems to primarily happen about the same time of year/weather:

light headedness, like a waking deja-vu type feeling - it comes with the typical sniffles, headaches etc. - but i never thought this might be a symptom
it's like the flu "bubble-head" sensation, like floating above reality

I mean, actually it's a bit enjoyable of a sensation when it comes and goes but it'd be more enjoyable if I was less paranoid sensationalist to think it's a brain-tumor or something like that

I haven't really correllated the pollen counts with the occurence of these symptoms which, yes I know, would be helpful in assessing
