guys do you think this is an effect of the lust spell I casted to the boy I was sleeping next to when I had a sleepover to my friends... before I casted the spell he was just really normal he does not even see me as attractive but when I started to cast it,,, he as slowly getting hotter and hotter by the minute and he was experiencing shortness of breath than he could not stand it when I'm far, he gets restless then his hand was always searching for me to cuddle me and he was also whispering my name all night.... do you think it was because of the spell I casted
I'd say so yes, thought it depends on the approach you took. If you opted to reach into his mind then it will have been you causing it.
If you cast intent then I'd say it's less likely it was you as your bog standard spell tends to be slower acting.
Either way, he clearly likes you. So with that said: does it matter?
I feel more information is necessary on the spell itself, it may be that the spell itself simply amplified an already existent attraction, or created one, in either case what you actually did is necessary information to determine which one is true, and what were you hopeful for will determine what actions you should take in the future.
