Brian Wilson has been laid to rest, almost two months after his death

Sharing a photo of pink, blue and purple flowers, she wrote on Instagram: "Today we laid my Daddy to rest. It was incredibly difficult to see that happen, but at the same time it gave more closure and more of a feeling of restful peace.

"The last eight weeks have been extremely challenging and like nothing I've ever experienced. I love and miss him so much and I wish he could come back."

The Wilson Phillips singer believes her dad has sent a number of "signs" since he passed away, which she has taken comfort in.

She continued: "There's so many signs that he gives me every day and I know that he's around ...he can hear me and he can see me. He makes that apparent. I'm so grateful for this.

"Today we had a couple of monarch butterflies that just would not leave the site. It was comforting and beautiful.

"I'm trying to deal with my emotions -they're so up and down. I know that he would want everybody to feel happy and not sad. He didn't like it when I cried."

And Carnie, 57, is grateful that her dad can live on and be remembered through his music.

She concluded: "I was talking with my dear friend Gunnar Nelson today who lost his Pop Ricky Nelson years ago and he reminded me that the world will have his music to sing to and remember him every single solitary day until we are all gone.

"This is a really special and a real heavy duty thought. It's much bigger than I can wrap my head around.

"For this I am grateful for though because I know it's the truth.

"So I just wanna say thank you... thank you Daddy for your beautiful contribution to so much happiness and real raw emotions that you have brought to people. Thank you to all the beautiful loving and supportive fans out there for honoring him. We share this together. God knows what we'd be without him. Love, Carnie (sic)"

It was previously explained that Brian - who had dementia - died of "respiratory arrest", caused by "decreased respiratory effort", which leads to a lack of oxygen.

Sepsis and cystitis were also listed as other causes of death, according to TMZ, which reports that obstructive sleep apnoea, neurodegenerative disorder, chronic respiratory failure and chronic kidney disease were cited as associated factors.
