Please help

I have heard this song now a couple of times but i dont know the name. i have searched everywhere and cant find much.
its a fast song sang by a woman.....theres a bit that goes 'i was laying in my bedroom counting the spiders on the wall' and the chorus is somethin like 'in your head, in your head what do you see, in your head' then 'its your imagination'

Does anyone know???

the title is zombie, by the cranberries

While I cannot personally find the song you're after I can wholeheartedly tell you it's not Zombie because:

1. Those areen't the lyrics.
2. Zombie isn't a fast song.



I should know, I'm a Cranberries fan
