Check with grammar please?

Hi there,

Can you check for me if these sentences are grammatical to you, please?

I don’t want to deceive myself. (Grammatical)

I don’t want deceiving myself. (Is this one grammatical?)

That bicycle obsessed me. (Is this grammatical?)

That bike or idea possessed me. (Is this grammatical?)

I am obsessed with that bicycle. (Grammatical)

I am possessed with that bike or idea. (Grammatical)

That bicycle is very obsessive. (Is this grammatical)

Btw, obsess and possess in here mean "attract and attractive" Am I correct, please?

Cheers.
