Advice on becoming a medium/more spiritual?

So I'm 17 and for as long as I can remember spirits have been attracted to me.From touching my face to throwing my things on the floor spirits have uaed these to get my attention.I can also feel a spirits prescense and I can describe it most closely to a kind of heaviness on me.Lastly I can sense peoples energys.After speaking about it with some of my friends and recently feeling a new spirit the other day I've decided that I want to try to be more in tune with this.By that I mean I want to be able to see them and communicate with them more efficiently instead of them just moving things when I speak.Does anyone know of any good websites or books I can read that can teach me more about this stuff or have any experience with this?Thank you to all answers.(and please do not say this is all in my head.My mothers even seen the damage that one of them did to my room while I was out)
