Miley Cyrus wishes she'd never woken up from a dream about her dead dog.

The 21-year-old is very close to her pets and was left devastated when her Alaskan Klee Kai pup Floyd passed away in April. She still appears to be suffering from the loss and opened up to her followers on Twitter.

"just woke up from a dream about Floyd. why did I have to wake up?" she wrote.

"I miss my best friend (sic)"

The singer has been having a tough time recently and was admitted to hospital following a severe allergic reaction to some antibiotics last month. It meant she had to cancel some dates of her Bangerz Tour, leaving her heartbroken.

Many people speculated that Miley's hospital stay was actually the result of a drug overdose. However, she strongly denies the rumors.

"I didn't have a drugs overdose. I took some antibiotics that a doctor gave me for a sinus infection," she cleared up the situation.

"My immune system was already low because I had a death in my family and was already down. What doesn't make it better is that people were online saying I'd done it with drugs but it's all good. I'm OK and I'm here."

The star seems to be back to her fun-loving self and has been posting pictures of herself partying with Sky Ferreira, who is her support act on tour. However, she did admit that she is missing her remaining pets.

"a lil homesick," she tweeted. "mostly missing my puppies (sic)"
